“And have, presumably, the exclusive use of the front bathroom adjoining your room?”
“I have.”
“Then the far front bedroom is unoccupied?”
“No one sleeps there, Mr. Bernard. The room has been turned into a sort of play—a sort of den for Mr. Joel Harrison. He keeps his stamp collection and his personal treasures there and potters about with his experiments.”
“Chemical experiments?”
“Oh, no. He has a workbench in there and sometimes makes things. At the moment his interest is in bows and arrows.”
“Oh!” said Bernard.
“Joel Harrison,” observed Miss Mount evenly, “is as harmless as a sweet-tempered child.”
“Thank you!” Bernard walked down the hall and tried the door of Joel Harrison’s den. It was locked. “I suppose there’s another door through your bathroom?” he asked. “I’d like to see the den.”
“You may come through my bedroom if you wish,” said Miss Mount patiently. “The door from my bathroom to the den is locked on my side, as Mr. Joel has a bathroom of his own adjoining his bedroom.” She opened her door for them.
