She opened the field kit she hadn't fully believed she'd need for Seal It. "How many people have been in and out of here since Grogan was missed?"

"Since I've been on board, just me. Prior, to the best of my knowledge, Sara Hunning, Steven Grogan and two ferry officers on board."

"There's an Out of Order sign on the door."

"Yeah."

"But she came in anyway."

"Nobody we've spoken to can absolutely confirm. She told the kid she was going in."

Sealed, Eve stepped into the first of the four stalls, waved a hand over the sensor. The toilet flushed efficiently. She repeated the gesture in the other three stalls, with the same results.

"Appears to be in order."

"It's human," Peabody told her, holding up her gauge. "Type A Negative."

"Some smears, but no drag marks," Eve murmured. She gestured toward a narrow utility closet. "Who opened that?"

"I did," Jake told her. "On the chance she - or her body - was in there. It was locked."

"There's only one way in and out." Peabody walked around to the sink area. "No windows. If that's Carolee Grogan's blood, she didn't stand up and walk out of here."

Eve stood at the edge of the blood pool. "How do you get a dead body out of a public restroom, on a ferry in the middle of the harbor, under the noses of more than three thousand people? And why the hell don't you leave it where it dropped in the first place?"

"It's not an answer to that," Jake began, "but this is a tourist boat. It doesn't carry any vehicles, has extra concession areas. People tend to hug the rails and look out, or hang in a concession and snack as they watch out the windows. Still, it'd take a lot of luck and enormous cojones to cart a bleeding body along the deck."
