“Nothing, except that it is possible someone is using Four Square Jane’s name in vain,” he said, “someone who was in a position to get one of the old labels she had used on her previous felonies. May I sit down?” he asked, for he had not been invited to take a seat. Claythorpe nodded curtly, and Dawes pulled a chair from the table and seated himself. “I have been reconstructing that crime,” he said, “and there are one or two things that puzzle me. In the first place, I am perfectly certain that no woman was in your office on the night the murder was committed.” Lord Claythorpe raised his eyebrows. “Indeed!” he said. “And yet the constable who was first in the room told me that he distinctly smelt a very powerful scent--the sort a woman would use. I also noticed it when I went into the room.” “So did I,” said Peter, “and that quite decided me that Four Square Jane had nothing to do with the business. A cool, calculating woman like Four Square Jane is certain to be a lady of more than ordinary intelligence and regular habits. She is not the kind who would suddenly take up a powerful scent, because it is possible to trace a woman criminal by this means, and it is certain that in no other case which is associated with her name was there the slightest trace or hint of perfume. That makes me more certain that the crime was committed by a man and that he sprinkled the scent on the floor in order to leave the impression that Four Square Jane had been the operator.” “What do you think happened?” asked Lord Claythorpe after a pause. “I think that Remington went to the office with the intention of examining the contents of the safe,” said Peter deliberately. “I believe he had the whole of the envelopes on the table, and had opened several, when he was surprised by somebody who came into the office. There was an argument, in the course of which he was shot dead.” “You suggest that the intruder was a burglar?” said Lord Claythorpe with a set face, but Peter shook his head. “No,” he said. “This man admitted himself to the office by means of a key. The door was not forced, and there was no sign of a skeleton key having been used. Moreover, the newcomer must have been well acquainted with the office, because, after the murder was committed he switched out the light and pulled up the blinds which Remington had lowered, so that the light should not attract attention from the street. We know they were lowered, because the constable on beat duty on the other side of the street saw no sign of a light. The blinds were heavy and practically light-proof. Now, the man who committed the murder knew his way about the office well enough to turn out the light, move in the dark, and manipulate the three blinds which covered the windows. I’ve been experimenting with those blinds, and I’ve found that they’re fairly complicated in their mechanism.” Again there was a pause.
