“Ordinarily when a man is murdered, we make a study of his contacts, of the people with whom he associates. Nine times out of ten, when robbery isn’t the motive, the murderer is someone who has had intimate contact with him. Nine tenths of Kosling’s associates are blind.”
“Now then, those associates gathered at around three-forty-five at Thinwell’s house, had their usual dinner and social gathering, and went home around nine. Therefore, if one of these blind men did it, he must have set the trap gun before the party, which accounts for the bat flying around the room.”
“Curtains down?” Bertha asked.
“Yes. That seems to be a peculiar obsession of blind men. They have a tendency to keep their curtain’s drawn.”
“Why?”
“Search me. Thinwell says he’s noticed it with Kosling in particular, several times.”
“You say Kosling telephoned Thinwell?”
“Yes.”
“Call from a pay station?” Bertha Cool asked.
“Yes.”
