Mr. Flexen studied the photographs and the report which stated this fact with a lively interest and a growing sense of its great importance. For one thing, it settled the question of suicide for good and all. Lord Loudwater had worn no glove. Also, it strengthened the case against the mysterious woman. She had come, apparently, from a distance, and probably in a motor-car. If she had driven herself down, she would be wearing gloves. Also, only a woman would be likely to be wearing gloves on a warm summer night. Indeed, coming from a distance by train, or car, she would certainly wear gloves. She would not dream of coming to an interview, with a man with whom she had been intimate and whom she wished to bend to her will, with hands dirtied by a journey. If that gloved hand had not been the hand of the mysterious woman, then the murder had been premeditated, and the murderer or murderess had put on gloves with the deliberate purpose of leaving no finger-prints. It _was_ the woman. In all probability it was the woman. Then Mr. Flexen's sub-conscious mind began to jog his intellect. Somewhere in his memory there was a fact he had noted about gloves, and that fact was now important in its bearing on the case. He set about trying to recall it to his mind. He was not long about it. Of a sudden he remembered that he had been a trifle surprised to perceive that Colonel Grey had been carrying gloves when he had found him in the rose-garden with Lady Loudwater. His surprise had passed quickly enough. He had decided that the life in the trenches had not weakened Colonel Grey's habit, as a fastidious man about town, of taking care of his hands. He remembered, too, that at his first interview with him he had observed that his hands were uncommonly well shaped and well kept. He did not suppose that Colonel Grey had come to the Castle on the night of the murder wearing gloves with the deliberate intention of killing Lord Loudwater without leaving finger-prints. But suppose that, as he came away from a distressing interview with Lady Loudwater, the knife on the library table had caught his eye and his gloves had been in his pocket? Mr. Flexen took out his pipe, lit it, and moved to an easy-chair to let his brain work more easily. He tabulated his facts. Colonel Grey had gone through the library window at about twenty minutes past ten. Hutchings had gone through the library window at half-past ten. The mysterious woman had gone through the library window at about ten minutes to eleven. She came out of the library window at about a quarter-past eleven after a violent quarrel with Lord Loudwater. Colonel Grey came out of the library window at about twenty-five minutes past eleven, after a distressing interview with Lady Loudwater, apparently in a very bad temper. James Hutchings had come out of the library window at about half-past eleven, also, if William Roper might be believed, furious.
