“Do you think the Inspector has any objections to our staying a while and listening?” asked Barry in a low tone, with an apprehensive glance toward the Inspector, who had stopped and was staring icily in their direction. “Don’t see why—” began Sampson worriedly, when Eve Ellis murmured “Shhh!” and they all became silent. “_Now—_” said the Inspector venomously, when the flurry had subsided, “this is the situation. Remember, you are now back in Monday evening. The curtain has gone up on the second act and the theatre is dark. There is a lot of noise from the stage and you are intent on the exciting sequences of the play.... Did any of you, especially those sitting in the aisle seats, notice anything peculiar, unusual or disturbing around or near you at that time?” He paused expectantly. There were puzzled, fearful shakings of the head. No one answered. “Think hard,” growled the Inspector. “You remember on Monday night I went down this aisle and questioned all of you in the same vein. Naturally I don’t want lies, and I can’t reasonably expect that you will tell me something startling now when you could remember nothing Monday night. But this is a desperate situation. A man was murdered here and we are frankly up against it. One of the most difficult cases we have ever encountered! In the light of such a condition, when we find ourselves against a blank wall with not the slightest idea where to turn—I am being honest with you as I expect you to be with me—I _must_ turn to you as the only members of the audience five nights ago who were in a position to see something important, if anything important occurred.... It has been my experience that often, under stress of nervousness and excitement, a man or woman will forget a little detail that returns to memory after a few hours, days, weeks of normalcy. It is my hope that something of the sort has taken place with you....” As Inspector Queen spoke, the words dropping acidly from his lips, the company lost its nervousness in its fascinated interest. When he paused, people put their heads together and whispered excitedly, shaking their heads at times, arguing in fierce, low tones at others. The Inspector waited in a resigned patience. “Raise your hands if you have something to tell me....” he said. A woman’s timid white hand fluttered aloft. “Yes, madam?” commanded Queen, pointing his finger. “Do you recall anything unusual?” A withered old lady rose embarrassedly to her feet and began to stammer in a squeaking voice. “I don’t know whether it’s important or not, sir,” she said tremulously. “But I do remember some time during the second act a woman, I think it was, walking down the aisle and a few seconds later walking up again.” “Yes? That’s interesting, madam,” commented the Inspector. “About what time was this—can you recall?” “I don’t remember the time, sir,” shrilled the old lady, “but it was about ten minutes or so after the beginning of the act.”
