At 9:50 exactly they rose, took their hats and coats and slipped out of the LL row into the clear space behind the orchestra. A number of people were standing—at which the Inspector smiled and blessed the power of the press beneath his breath. The white-faced usherette, Madge O’Connell, was leaning stiffly against a pillar, staring unseeingly ahead. The Queens, espying Manager Panzer in the doorway of his office beaming delightedly at the crowded auditorium, made their way towards him. The Inspector motioned him inside and rapidly stepped into the little anteroom, Ellery close behind. The smile faded from Panzer’s face. “I hope you’ve had a profitable evening?” he asked nervously. “Profitable evening? Well—it depends upon what you mean by the word.” The old man gestured briefly and led the way through the second door into Panzer’s private office. “Look here, Panzer,” he said, pacing up and down in some excitement, “have you a plan of the orchestra handy which shows each seat, numbered, and all the exits?” Panzer stared. “I think so. Just a moment.” He fumbled in a filing-cabinet, rummaged among some folders and finally brought out a large map of the theatre separated into two sections—one for the orchestra and the other for the balcony. The Inspector brushed the second away impatiently as he and Ellery bent over the orchestra-plan.[5] They studied it for a moment. Queen looked up at Panzer, who was shifting from one foot to another on the rug, evidently at a loss to know what would be required of him next. [5] The plan illustrated in the frontispiece and drawn by Ellery Queen was designed from Manager Panzer’s map.—The Editor. “May I have this map, Panzer?” asked the Inspector shortly. “I’ll return it unharmed in a few days.” “Certainly, certainly!” said Panzer. “Is there anything else I can do for you now, Inspector?... I want to thank you for your consideration in the matter of publicity, sir—Gordon Davis is extremely pleased at the ‘house’ to-night. He asked me to relay his thanks.” “Not at all—not at all,” grumbled the Inspector, folding the map and putting it in his breast-pocket. “It was coming to you—what’s right is right.... And now, Ellery—if you’ll come along.... Good night, Panzer. Not a word about this, remember!” The two Queens slipped out of Panzer’s office while he was babbling his reassurances of silence. They crossed the rear of the orchestra once more, in the direction of the extreme left aisle. The Inspector beckoned curtly to Madge O’Connell. “Yes,” she breathed, her face chalky. “Just open those doors wide enough to let us through, O’Connell, and forget all about it afterward. Understand?” said the Inspector grimly. She mumbled under her breath as she pushed open one of the big iron doors opposite the LL row. With a last warning shake of the head the Inspector slipped through, Ellery following—and the door came softly back into place again. * * * * *
