A muddy path only a foot wide wound between the long grass and sagging birch trees to the top of the slope. The wet ground sucked at Stride’s boots, and he slipped as he climbed, falling to his knees and nearly losing his gun. He had to sink his free hand in the dirt to push himself up. Maggie followed behind him, swearing as her heels got trapped. She kicked them off, leaving herself in bare feet.

They reached the crown of the hill, where the expanse of beach and lake opened up below them. Superior was a living thing, violent and huge, invading the puny finger of sand. Around them, the trees yawned and spun. Lightning popped in their eyes, and the circling beam of the Superior lighthouse flashed through the darkness out on the water.

At first, the beach looked empty.

“Where are they?” Maggie screamed, cupping her hand beside her mouth.

“I don’t see them!” The lightning broke again, and Stride pointed. “Wait, there they are!”

Fifty yards away, looking no larger than dolls, Clark Biggs and Finn Mathisen were on opposite sides of a giant trunk of driftwood. Finn lay sprawled on the ground, half his torso propped against the tree. Clark stood behind him. When the next flash of lightning illuminated the beach, they realized that Clark held a baseball bat in his hands and was preparing to swing with deadly intent at the back of Finn’s head.

“Stop!” Maggie shouted.

She might as well have been mute. Clark couldn’t hear a thing.

“Clark! Stop!”

Stride aimed his Glock into the sky and squeezed off a round. To him, with the gun by his ear, the report sounded loud, but he wasn’t sure the shot could be heard over the wind, rain, thunder, and surf. For a few long seconds, the beach was dark, and they were blind. When they could see through the next streak of light, they saw Clark, stopped, the bat poised high above his head, as he stared directly at them on top of the hill. Stride half expected him to swing, but Clark froze, hesitating at the brink.

Finn’s face was turned toward them. He was alive.

Stride stumbled down the slope to the flat stretch of wet sand and rye grass. He splashed through pooled water with Maggie on his heels and stopped ten feet from the slab of driftwood. Stride pointed his Glock at the ground, but he held it out from his body where Clark could see it. He studied Finn and saw that the man was badly hurt, his shoulder broken, his left hand pressed frantically on his disjointed knee, his face twisted in agony. He had bitten his lip so hard that it was bleeding.

“Son of a bitch,” Maggie murmured. Then she said loudly, “Clark! Don’t do this! Put the bat down!”

Clark’s face was hard as stone. His eyes were black. He shook his head.

“This is your life,” Maggie told him. “Don’t destroy it. Mary wouldn’t want you to do that.”
