His hands were opening and shutting with nervous twitches on the top of the desk.
Jimmie Dale's lips curled.
"But"-- Jimmie Dale was clipping off his words now viciously--"neither you nor the Weasel were willing to trust the other implicitly--perhaps you know each other too well.

You were unwilling to turn over the map until you had received your share of the money, and you were equally unwilling to turn it over until you were SAFE; that is, until you had engineered your fake robbery even to the point of notifying the police that it had been committed; the Weasel, on the other hand, had some scruples about parting with any of the money without getting the map in one hand before he let go of the banknotes with the other.

It was very simply arranged, however, and to your mutual satisfaction.

While you robbed your own house this evening, he was to get half the money in advance from Hamvert, giving Hamvert to understand that HE had planned to commit the robbery himself to-night.

He was to come out here then, receive the map from you in exchange for your share of the money, return to Hamvert with the map, and receive in turn his own share.
