For I couldn't make any sense of the puzzle: I wondered most of all what H.M. made of it. In the matter of expressing opinions about anything, it is usually almost impossible to stop him. But he had said nothing. Of course, it may have been the telephone. Like myself, H.M. dislikes talking at length over the telephone: he prefers talking face to face: and protracted conversations on a wire make him fidget. We were both inclined to throw the facts at each other quickly and disjointedly. Yet I had not even been able to learn what it was Serpos had stolen out of the safe, something which seemed to be so valuable and over which so much fuss had been made.
And that was nothing compared to the curious circumstances of the murder. Back at "The Larches" in Valley Road, a man sat dead of strychnine poisoning. The centre of the puzzle was clear enough — obviously he had mixed the dose himself, mistaking it for bromide, in a glass of particularly nauseous mineral-water — but the edges were clouded. We had a series of events like this:
This morning, at breakfast, Hogenauer told Bowers he was going to Bristol, that he had made certain Keppel would be out, and that he meant to pay a secret visit to Keppel's hotel. He also warned Bowers to expect a visitor at "The Larches" that night, presumably Keppel himself. During the morning, Hogenauer wrote a letter to someone he addressed as "Your Excellency," beginning at one fragment with a reference to "fast planes," mentioning that he would "make the attempt to-night" on an envelope in Keppel's desk, and breaking off with a remark about valuable knowledge. Keppel was now believed to be in Moreton Abbot. On the same morning, he came to see Hogenauer, and when he left — according to Bowers — Hogenauer gave him something which locked like "an envelope folded in half." Hogenauer was last seen alive by Bowers at six o'clock, when Bowers left the house. At this time Hogenauer warned Bowers of a prospective visitor that night, adding that Bowers would probably not see him. Hogenauer drank the poison about a quarter to nine o'clock. His body was discovered, a little over a half an hour afterwards, by Mrs. Antrim. The door of the room was locked on the inside. Inside the room (a) a number of articles of furniture had been changed round, (b) a light placed on the mantelshelf indicated a gap in the shelves from which two books on aeronautics were missing, and (c) on Hogenauer's desk were four pairs of cuff-links.
At this point I realized that I must stop puzzling and get to business. It would not do to delay too long in getting to the station. I unwrapped my bundle. I put on waistcoat and tie again, and commenced buttoning up the policeman's tunic for the second stage of my adventures. My watch, still safe in the waistcoat pocket, said that it was now fifteen minutes past eleven. Over the top of a rise appeared the
head-lamps of a car, crawling leisurely, and it was now time to act. I tossed away the newspaper — which had served several purposes that night since Mrs. Antrim said she had found it in the scullery-and, as it flopped wide in the hedge, it served its last purpose. Something white fluttered
out of the now loose pages, and fell on the pavement.
I picked it up. It was a £ 100 bank-note.

The Devil in the Bag
"To the railway-station?" said the man in the car. "Yes, certainly: glad to take you. Jump in. As a matter of fact, I'm going there myself."
