“The other disturbing factor concerning Frances—the discovery of her bag in Field’s clothes—was plausibly explained by her dropping it in the natural excitement of the moment when the drunken lawyer approached her. This was later confirmed by Jess Lynch’s testimony to the effect that he saw Field pick up Frances’ bag. Poor girl—I feel sorry for her.” The Inspector sighed.
“To get back to the hat—you’ll notice we always return to that blasted top-piece,” resumed Queen, after a pause. “I never knew of a case in which a single factor so dominated every aspect of the investigation. … Now mark this: Of the entire cast Barry was the only one who left the Roman Theatre Monday night dressed in evening clothes and tophat. As Ellery watched at the main door Monday night while the people were filing out, his mind characteristically registered the fact that the entire cast, except Barry, left the theatre wearing street clothes; in fact, he even mentioned this to Sampson and me in Panzer’s office later, although at the time neither of us realized its full significance. … Barry was therefore the only member of the cast who could have taken away Field’s tophat. Think this over a moment and you will see that, in view of Ellery’s hat-deductions, we could now pin the guilt to Barry’s shoulders beyond the shadow of a doubt.
“Our next step was to witness the play, which we did the evening of the day on which Ellery made the vital deductions—Thursday. You can see why. We wanted to confirm our conclusion by seeing whether Barry had the time during the second act to commit the murder. And, amazingly enough, of all the members of the cast, Barry was the only one who did have the time. He was absent from the stage from 9:20—he opened the business of the act and left almost at once—until 9:50, when he returned to the stage to remain there until the act ended. This was incontrovertible—part of a fixed and unchanging time-schedule. Every other player was either on the stage all the time or else went on and off at extremely short intervals. This means that last Thursday night, more than five days ago—and the whole case took only nine days to consummate—we had solved our mystery. But solving the mystery of the murderer’s identity was a far cry from bringing him to justice. You’ll see why in a moment.
“The fact that the murderer could not enter until 9:30 or thereabouts explains why the torn edges of LL32 Left and LL30 Left did not coincide. It was necessary for Field and Barry, you see, to come in at different times. Field could not very well enter with Barry or even at a noticeably late hour—the matter of secrecy was too important to Barry, and Field understood, or thought he did, how necessary it was for him to play the secret game.
“When we pinned the guilt on Barry Thursday night, we resolved to question subtly the other members of the cast as well as workmen backstage. We wanted to find out, of course, whether anyone had actually seen Barry leave or return. As it happened, no one had. Everybody was busy either acting, redressing, or working backstage. We conducted this little investigation after the performance that night, when Barry had already left the theatre. And it was checkmate, right enough.
“We had already borrowed a seating-plan from Panzer. This map, together with the examination of the alleyway on the left and the dressing-room arrangement backstage—an examination made directly after the second act Thursday night—showed us how the murder was committed.”
Sampson stirred. “I’ve been puzzling my wits about that,” he confessed. “After all, Field was no babe-in-the-woods. This Barry must be a wizard, Q. How did he do it?”
“Every riddle is simple when you know the answer,” retorted the Inspector. “Barry, whose freedom began at 9:20, immediately returned to his dressing-room, slapped on a quick but thorough facial disguise, donned an evening-cloak and the tophat which was part of his costume—you’ll remember he was already dressed in evening-clothes—and slipped out of his room into the alley.
“Of course you can’t be expected to know the topography of the theatre. There is a series of tiers in a wing of the building backstage, facing the left alley, which is made up of dressing-rooms. Barry’s room is on the lowest tier, the door opening into the
