"That all?"

"That's all, right now. But I've got a suspicion she knows more than we think. When she makes up her mind to talk, she'll say something!—Mr. Hastings," Crown added, as if he imparted a tremendous fact, "that woman's smart! I tell you, she's got brains, a head full of 'em!"

"So I judged," the detective agreed, drily. "By the way, have you seen Russell again?"

"Yes. There's another thing. I don't see where you get that stuff about his weak alibi. It's copper-riveted!"

"He says so, you mean."

"Yes; and the way he says it. But I followed your advice. I've advertised, through the police here and up and down the Atlantic coast, for any automobile party or parties who went along that Sloanehurst road last night between ten-thirty and eleven-thirty."

"Fine!" Hastings congratulated. "But get me straight on that: I don't say any of them saw him; I say there's a chance that he was seen."

The old man went back, not to examination of Hendricks' parcel, but to further consideration of the possible contents of the letter that had been in the grey envelope. Russell, he reflected, had been present when Mildred Brace mailed it, and, what was more important, when Mildred started out of the apartment with it.

He made sudden decision: he would question Russell again. Carefully placing Hendricks' package of dust and lint in a drawer of the table, he set out for the Eleventh street boarding house.
