"That's just it!" says the policeman.
"Did they send you to tell me?" says Mary.
"No; they don't know I'm come," says he.
Mary said "Ah!" to this, and a little smile came over her face. She looked up at him with that same smile—you see, we heard the story after, from him as well as her, so I've got both sides of the picture, so to speak—and she says, "You don't think I've had anything to do with that, I hope!"
"No," says he, "I don't. I'm sure you haven't."
"I didn't know of the watch being lost till this moment," says Mary.
"No," says he, "I'm sure you didn't. It isn't you!"
And there was something in the way he stopped a moment, and then said the "you," as if to mark that though it wasn't her it was somebody. It brought up the thought of Walter with a blow. What did he mean? Mary's smile went, and she said—
"I don't understand."
"There's one or two things I don't understand neither," says the policeman. "And I've come to you to help me. Maybe you can explain 'em."
