But this impression, if impression it were, was of short duration. No sooner had this physically weak but extremely wise old man entered upon the scene than his mental power became evident to every person there. Timorous hearts regained their composure, and the Curator--who in his ten years of service had never felt the burden of his position so acutely as in the last ten minutes--showed his relief by a volubility quite unnatural to him under ordinary conditions. As he conducted the detectives across the court, he talked not of the victim, as might reasonably be expected, but of the woman who had been found leaning over her with her hand on the arrow. "We think her some escaped lunatic," he remarked. "Only a demented woman would act as she does. First she denied all knowledge of the girl. Then when she was made to see that the arrow sticking in the girl's breast had been taken from a quiver hanging within arm's reach on the wall and used as lances are used, she fell a-moaning and crying, and began to whisper in the poor child's senseless ear." "A common woman? One of a low-down type?" "Not at all. A lady, and an impressive one, at that. You seldom see her equal. That's what has upset us so. The crime and the criminal do not seem to fit." The detective blinked. Then suddenly he seemed to grow an inch taller. "Where is she now?" he asked. "In Room B, away from the crowd. She is not alone. A young lady detained with the rest of the people here is keeping her company, to say nothing of an officer we have put on guard." "And the victim?" "Lies where she fell, in Section II on the upper floor. There was no call to move her. She was dead when we came upon the scene. She does not look to be more than sixteen years old." "Let's go up. But wait--can we see that section from here?" They were standing at the foot of the great staircase connecting the two floors. Above them, stretching away on either side, ran the two famous, highly ornamented galleries, with their row of long, low arches indicating the five compartments into which they were severally divided. Pointing to the second one on the southern side, the Curator replied: "That's it--the one where you see the Apache relics hanging high on the rear wall. We shall have to shift those to some other place just as soon as we can recover from this horror. I don't want the finest spot in the whole museum made a Mecca for the morbid and the curious." The remark fell upon unheeding ears. Detective Gryce was looking, not in the direction named, but in the one directly opposite to it. "I see," he quietly observed, "that there is a clear view across. Was there no one in the right-hand gallery to see what went on in the left?" "Not that I have heard of. It's the dullest hour of the day, and not only this gallery but many of the rooms were entirely empty." "I see. And now, what about the persons who were here? How many of them have you let go?"
