“It must be the top drawer,” he reflected. “So she carries the keys in a pocket on the right. All in one bunch on a steel ring.... And there’s one key there, three times as big as all the others, with deep notches; that can’t be the key of the chest of drawers... then there must be some other chest or strong-box... that’s worth knowing. Strong-boxes always have keys like that... but how degrading it all is.”

“Here, sir: as we say ten copecks the rouble a month, so I must take fifteen copecks from a rouble and a half for the month in advance. But for the two roubles I lent you before, you owe me now twenty copecks on the same reckoning in advance. That makes thirty-five copecks altogether. So I must give you a rouble and fifteen copecks for the watch. Here it is.”
