She could hear her own voice, too. “Stop!”

But nothing else. Her memory was a blank space.

She found herself resenting what Jason had done, even if she’d asked him to do it. She’d been there to witness her father’s last moments, and now that walk on the trail had been stripped from her brain.

This is what you do to everyone else, her mind whispered.

She’d never understood what her patients experienced when they lay on her chaise and stared at the images she’d made for them and responded to her subliminal suggestions. She’d never known what it felt like, afterward, to have part of your past stolen away. This was her chance to look through the other end of the microscope. She didn’t like what she saw.

“Are you okay?”

She realized Frost was staring at her, his forehead wrinkled with concern.

“Yes, I’m fine. I’m not going to have another seizure, if that’s what you’re worried about.”

“You looked far away,” Frost said, “and not in a happy place.”

Frankie shivered in the rain. “I’m questioning things. Some days I wonder if I’ve done more harm than good in my life.”

Frost’s eyes were curious, but he didn’t push her for details. She was grateful for that. He went back to his binoculars.

“Newman’s getting a call,” he told her. And then a minute later, “Come on, he’s on the move.”

Frost led her across the wet grass back to his Suburban, which was parked on Fell Street. Across the park, Frankie could see the door sliding up on the garage of Darren’s Victorian house. His red Lexus inched down the driveway, and when the traffic was clear, he backed onto Oak Street. The one-way street headed east, away from them, and Darren made an immediate right. His car disappeared.

Frost accelerated toward the point of the Panhandle and cruised through the yellow light into a left turn. Sutro Tower loomed on the hillside ahead of them. He sped to the next block and did another left to lay chase, but almost immediately, he hissed, “Get down!”

Darren’s Lexus sped toward them, no more than half a block away. Frankie slid as far as she could below the dash, and Frost dropped his visor to block his face. The two vehicles whipped by each other in opposite directions. Frost eyed his mirror, and Frankie took a quick look backward over the seat. She saw the Lexus make a right turn. Frost did a U-turn and followed.

They spotted Darren’s Lexus three cars ahead of them.

“He’s heading into Golden Gate Park,” Frost said.
