When shall I tell him?

Life, Maddy reflected, was full of weird twists and turns. It seemed cruel to keep from Zack one moment longer than she absolutely had to the wonderful news that Theresa was all but his. So why was she still hugging it to herself, like a miser jealously guarding his pot of gold? The custody papers were sitting right there in her purse, the purse she'd left safely locked in the trunk of her car.

Why was it so hard to tell him?

Because she knew perfectly well why Zack had asked her to marry him. He'd hoped a wife would help to swing the adoption board in his favor. If he were assured of gaining custody of Theresa without a wife, would he still want to marry her? Zack was a decent, compassionate man. He would never be so cruel as to withdraw his proposal just because the situation had changed.

But the situation had changed. And Maddy knew that, regardless of Zack's principles, she couldn't go through life married to someone who didn't love her.

Any way you sliced it, it was going to be a difficult and painful thing to resolve.

It had been enough that Zack needed her. Now even that would be gone.

"Hurry up, Maddy!" Theresa called. She and Zack were waiting for her to catch up. Theresa held out her hand, dancing with impatience. "Give me your hand!"

With Zack and Maddy each holding one of her hands, Theresa took two running steps and lifted both feet off the ground, swinging suspended between the two grown-ups.

Maddy laughed. "Don't you think you're a bit too big to do that?"

"Aw, gee," Theresa grumbled. "How come I'm always either too small or too big!"

"The universal lament of the child," Zack said dryly. "That's the breaks, squirt."

They were ahead of the bulk of the holiday crowd, which would come in later for the fireworks show, on shuttle buses from town. Even so, picnickers had already claimed the available tables, so they staked out a nice spot under a sycamore tree on the gently sloping banks of the lake. It was directly opposite the softball field, where the pyrotechnics experts were busy setting up for the big display later that evening. They would have a good view without being close enough to sustain permanent hearing damage.

Theresa was a little disappointed with the lake at first. The boats were only ugly old canoes, not pretty white sailboats like the ones in her picture. But when Zack told her that the boats in her picture were just toys and that you could actually take a ride in these ugly old canoes, she brightened right up, and of course wanted to go in a boat immediately.

So all three of them donned bright orange life jackets and spent the early part of the afternoon paddling ineptly around the lake, dodging other canoes and paddle boats, and drenching each other with water from their paddles.

When they had collapsed back on their blanket, laughing and half soaked, Zack reached for his mystery bundle and drew it forth with a flourish.

"Oh, boy," Theresa cried, bouncing up and down on her heels. "Now we get to see the surprise! What is it? Can I see? Hurry up, Zack!"

"Ah-ah. Cool it, squirt. All in good time." Zack was shamelessly milking his moment.

Maddy watched them bend together over the package and felt a surge of love wash through her like a tidal crest. She was glad, at that moment, that neither of them happened to be watching her face. She lowered her head until the spasm had passed, then wiped her cheeks quickly and openly with her hands. Her face was spattered with water, anyway, from the canoe's paddles.

They were having such a wonderful time, she thought, even without knowing that everything was going to be all right. She didn't need to tell him yet. She would wait a little longer. She could be a part of them for just a little longer…

"It's a kite!" Theresa shrieked. "A kite, just like in the picture! Can we make it fly, Zack? Can we?"

"That's the idea," he muttered, looking perplexed as he tried to decipher the assembly instructions. He cast Maddy a look of appeal.

She sighed and gazed skyward, then reached for the jumbled pieces. "Piece o' cake," she said smugly a few minutes later as she handed back the assembled kite.

"Hmm," Zack said with grudging admiration. "How'd you do that?"

"Maddy knows how to make things," Theresa explained. "She makes puppets all the time, don't you know that?"

"Handy person to have around," he said softly, smiling into Maddy's eyes. It was the first time all day he'd allowed himself to meet her eyes, and in that moment she saw the fear he'd been trying so hard to hide. And something else too. Something elusive, like a familiar face glimpsed in a crowd. She caught her breath and tried to hold on to whatever it was she'd seen, but it was gone too quickly, hidden behind that smoky veil.

He leaned over to give her a thank-you kiss. Then he and Theresa were dashing off to find an open space in which to launch their kite.

Maddy took a deep breath and opened the picnic hamper. It was their day, Zack and Theresa's. She was the outsider. They didn't really need her at all.

They came trooping dejectedly back to the blanket about half an hour later-minus the kite.

"A tree ate it," Theresa said sadly.

"A kite-eating tree." Zack looked thoroughly disgusted. "There really is such a thing, can you believe it? Never mind, squirt," he said, ruffling Theresa's hair. "Next time we'll go to a park with wide-open spaces!"

Next time. He threw Maddy a look that tore at her heart. She almost, almost, blurted out the truth to him then and there. But Theresa began exclaiming over the array of picnic goodies Maddy had laid out, and the moment passed.

They ate fried chicken and potato chips, and carrot and celery sticks and black olives, and fresh strawberries as big as small apples and so sweet, they needed no sugar at all. Maddy had bought them at the roadside stand just down the street from her place. There was a bag of peanut-butter cookies, too, from Dottie Frownfelter.

"Because I made 'em," Theresa announced, then conscientiously amended, "Well, I helped."

"Let me guess," Zack said. "You smashed 'em, right?"

"Right," Theresa said, giggling.

After they'd finished eating, Theresa wanted to go out in the canoes again.

"Not now," Zack murmured, yawning as he settled himself with his back against the sycamore tree. "Don't you know you're supposed to take a nap after a Fourth of July picnic?"

"Come on, Zack." Theresa tugged at his hand, then gave up, recognizing a lost cause when she saw one. "Can I go by myself, then? I'm big enough."

Zack opened one eye and gave her a stern glare. "No, you're not. Don't you go near those boats without me, understand? Hey," he added persuasively as Theresa's chin developed a stubborn tilt. "You know, those fireworks are going to keep us up way past our bedtime. Come here and help me catch some z's."

"I'm not sleepy," Theresa said, but curled up next to Zack anyway, and in a remarkably short time was out like a light…

"Hey, sweetheart. Wake up." Zack's words made soft, moist puffs against Maddy's temple. His fingers were stroking her throat. She opened her eyes and found his face inverted an inch or so above hers. "Sorry to disturb you, babe. I need your keys."

"What…?"

"Shh. Theresa's still asleep. Car keys. I thought I'd take a bunch of this picnic stuff back to the car right now, so we don't have so much to carry later."

"Oh. Okay." She fumbled in her pocket for the keys to her car. "Zack… bring back my purse, okay? I left it in the trunk."

"Sure." He gave her a lingering, upside-down kiss, and whispered, "Sweet dreams…"

Maddy woke suddenly, with that sweaty, shaky, adrenaline surge that accompanies an already-forgotten nightmare. She sat up trembling and disoriented, staring around her, terrified without knowing why.

Then suddenly, with shattering clarity, she knew why.

She was alone. The blanket was empty. Theresa was gone.

The nightmare terror ebbed slowly with the return of full consciousness, leaving her concerned and mildly annoyed, but not really worried. Theresa couldn't have gone far-wouldn't have gone far. She'd just gone off, in her independent little way, to do some exploring on her own.

"Can I go by myself? I'm big enough."

No. She wouldn't try to take out one of the boats by herself. Zack had expressly told her to stay away from them.

Maddy stood up and walked a little way down the slope toward the docks, shading her eyes against the glare of the setting sun. Could Theresa get past the men who managed the canoe rentals? Probably she could. But she wouldn't disobey Zack… would she? Then Maddy remembered Carleen saying, "Sometimes she doesn't mind…" And she remembered that stubborn little chin…

She looked around for Zack, then recalled that he'd gone to the car. How long ago had that been? She had no idea how much time had passed, how long she'd been dozing. Long enough, certainly, for a little girl to wake up and completely vanish from her sight.

Maddy began to call, "Theresa? Theresa!" as she walked down toward the lake.

There were several canoes still out on the water, dark silhouettes on a surface of rippled bronze, but she couldn't see against that glare. She called again, cupping her hands around her mouth to make a mega-phone, sending her voice across the water.

A thin, childish voice answered. One tiny figure lifted an arm to wave, then stood up. "Hi, Maddy. Look at me! Look what I can do!"

"Theresa! Oh… God." Maddy clapped both hands over her mouth and looked frantically around her. Several people were glancing her way, apparently wondering what was happening. "Theresa, honey, stay there! Sit down! Do you hear me? Sit down!"

Some of Maddy's urgency seemed to reach the little girl. Suddenly she appeared confused. As she wavered uncertainly between standing and sitting, her paddle slipped from her grasp and fell into the water. She reached for it-an automatic reflex-and then, frightened by the canoe's wobble, tried to regain her balance. It was too late. As Maddy watched in stony horror, Theresa toppled into the gilded water.

She made a pathetically insignificant splash. Maddy's anguished cry covered it completely. Maddy remained frozen, nailed to the end of the dock, until she saw a dark head bob to the surface. Then she closed her eyes tightly, held her nose, and jumped.

As she hit the water she had only one thought: Not again. Zack can't lose another child like this. Dear God, not again…

Zack was coming down the slope through the sycamore trees when he heard Maddy's scream. It took him a fraction of forever to locate her, poised there on the end of the dock, and another eternity before he'd identified the reason for her cry. When he saw Maddy jump, he whispered, "No…!"Maddy's purse slipped from his hand as he began to run.

He flew down the hill and thundered onto the dock, scattering the gathering crowd like so many pigeons.

Theresa was treading water, bless her heart, just the way he'd taught her. Zack shouted at her, "That's it, baby, you're doing fine. Just hang in there. I'm coming!"

Hang in there, baby. Please.

Maddy was floundering through the water with a kind of frantic resolve that had already carried her far beyond her limits. Zack swore with the kind of virtuosity that only comes with sheer emotional overload. The idiot! The crazy idiot. She'd learned a lot in three weeks, but there was no way in the world she'd ever make it out as far as that canoe, much less back again with Theresa! What did she think she was going to do? They'd both drown!

They'd both drown.

"Call the paramedics!" he bellowed at the nearest bystander, and launched himself into the water like a human torpedo.

He'd never pushed himself so hard in his life. He wasn't swimming for gold or records now-he was swimming for two people's lives. The lives of the two people he loved most in the world.

As he churned through the water, Zack was torn between the need to keep those two heads in his sight, and the knowledge that he'd gain speed by keeping his head down. He tried to locate them whenever he took a breath, but it was so hard to see.

Theresa's eyes were his beacon, his lighthouse. Hang on, baby, he pleaded silently. I'm coming. Don't let go. Don't give up. …"

He'd lost sight of Maddy. He couldn't see her anymore.

He reached Theresa, and she clung to his neck. Her thin little body was shaking with cold and fear.
