man's book, the pennies for which he punctiliously paid over the counter. Having no cheque forms with him, he explained, he might find them useful if he could come across some friend who could provide the cash he wished to use that night. And having completed this business so far, this charming new customer of the bank made off into the night."
"And is that all you know of his movements?"
"Yes, as yet. He seems to have made no very definite excuse to the manager for wanting the money in such a hurry—just said something had occurred which made cash necessary, and was very polite and apologetic, generally. The manager formed a notion that it must be for some gambling purpose—he fancied that Mayes said something distantly alluding to that, but wasn't sure."
"Did you ask about the address given to the bank?"
"Of course; but there we gained nothing. The manager couldn't remember it exactly, and the books, of course, were locked up. But we know it already—for what the manager could remember was that it was an office address, and somewhere near Barbican! So that we are back at the Barbican den again, where I am going now, with Plummer, to give a day to a minute investigation of the whole place. Meanwhile a watch is being set at the bank in Holloway."
