“From the very beginning of this case,” Miss Dammers proceeded, imperturbable as ever, “I was of the opinion that the greatest clue the criminal had left us was one of which he would have been totally unconscious: the unmistakable indications of his own character. Taking the facts as I found them, and not assuming others as Mr. Sheringham did to justify his own reading of the murderer’s exceptional mentality—” She looked challengingly towards Roger.
“Did I assume any facts that I couldn’t substantiate?” Roger felt himself compelled to answer her look.
“Certainly you did. You assumed for instance that the typewriter on which the letter was written is now at the bottom of the Thames. The plain fact that it is not, once more bears out my own interpretation. Taking the established facts as I found them, then, I was able without difficulty to form the mental picture of the murderer that I have already sketched out for you. But I was careful not to look for somebody who would resemble my picture and then build up a case against him. I simply hung the picture up in my mind, so to speak, in order to compare with it any individual towards whom suspicion might seem to point.
“Now, after I had cleared up Mr. Bendix’s reason for arriving at his club that morning at such an unusual hour, there remained so far as I could see only one obscure point, apparently of no importance, to which nobody’s attention seemed to have been directed. I mean, the engagement Sir Eustace had had that day for lunch, which must subsequently have been cancelled. I don’t know how Mr. Bradley discovered this, but I am quite ready to say how I did. It was from that same useful valet who gave Mrs. Fielder-Flemming so much interesting information.
“I must admit in this connection that I have advantages over the other members of this Circle so far as investigations regarding Sir Eustace were concerned, for not only did I know Sir Eustace himself so well but I knew his valet too; and you may imagine that if Mrs. Fielder-Flemming was able to extract so much from him with the aid of money alone, I myself, backed not only by money but by the advantage of a previous acquaintance, was in a position to obtain still more. In any case, it was not long before the man casually mentioned that four days before the crime Sir Eustace had told him to ring up Fellows’s Hotel in Jermyn Street and reserve a private room for lunch-time on the day on which the murder subsequently took place.
“That was the obscure point, which I thought it worth while to clear up if I could. With whom was Sir Eustace going to lunch that day? Obviously a woman, but which of his many women? The valet could give me no information. So far as he knew, Sir Eustace actually had not got any women at the moment, so intent was he upon the pursuit of Miss Wildman (you must excuse me, Sir Charles), her hand and her fortune. Was it Miss Wildman herself then? I was very soon able to establish that it wasn’t.
“Does it strike you that there is a reminiscent ring about this cancelled lunch-appointment on the day of the crime? It didn’t occur to me for a long time, but of course there is. Mrs. Bendix had a lunch-engagement for that day too, which was cancelled for some reason unknown on the previous afternoon.”
“Mrs. Bendix!” breathed Mrs. Fielder-Flemming. Here was a juicy triangle.
Miss Dammers smiled faintly. “Yes, I won’t keep you on the tenterhooks, Mabel. From what Sir Charles told us I knew that Mrs. Bendix and Sir Eustace at any rate were not total strangers, and in the end I managed to connect them. Mrs. Bendix was to have lunched with Sir Eustace, in a private room, at the somewhat notorious Fellows’s Hotel.”
