As soon as the verdict had been rendered, Detective Sergeants Johnson and Richardson, who had been detailed by Superintendent of Police Walton to attend the inquest, reported to him for further instructions. They briefly repeated the testimony and especially the startling evidence of Wright. When they had finished the chief said:
“What do you make of it?”
“The man in the brown overcoat is the murderer,” said Johnson.
“The man in the brown overcoat had nothing to do with it; but Wright knows a great deal more than he has told,” was Richardson’s analysis.
Walton looked out of the window a couple of minutes without speaking. “The person who committed the murder,” he said, as if he were talking to himself more than to his listeners, and without looking at either, “was expected to call at the office that evening by Marchburn, who came back about the time the clerks were preparing to leave, on purpose to keep his appointment. All the doors were locked. Either the visitor must have had a duplicate key, or else Marchburn left one of the doors open, or they had a private signal. Any one of a dozen persons might have been able to open the door with a duplicate key; but I don’t see anything to point in that direction. Marchburn would hardly be likely to leave the door open for his expected visitor, so it is evident the doors were kept locked, and when the prearranged signal was given Marchburn opened the door to his murderer. Who was the murderer and what was the motive? It was not money, because no valuables were taken, and the clerks say that neither papers nor anything else were disturbed. The murder was either the result of a sudden burst of passion, or else it was premeditated, and something forced the murderer to do then what had long been contemplated. There was a very strong motive. Find the motive and you find the—”
“The murderer,” interrupted Richardson.
“The murderess,” continued the chief as calmly as if he had not heard the interruption.
“A woman?” cried his listeners simultaneously.
“Certainly, a woman; it is a woman’s crime. From the time when Rogers and Harding left until the discovery of the body was a scant hour. To avoid all possible risks of interruption, Marchburn did not arrange the interview until after five, so that between that hour and six he was shot. At six he was dead, and the doctor testified he must have been dead between fifteen and thirty minutes when he was called in. So that fixes the time of the shooting between half past five and six. Marchburn expected a woman to call upon him that night, because he would not have made such careful preparations for secrecy if his visitor had been a man. He did not want his clerks to see his caller. The time between her calling and the shooting was too short for them to have quarreled; but it was long enough for her to have made her demand and to have been refused by Marchburn. Then she shot him.”
