"What kind of death?" was the harsh reply. "We don't send detectives in cases of heart-failure or simple accident. Is it an accident?"

"No—no—hardly. It looks more like an insane woman's attack upon a harmless stranger. It's the oddest sort of an affair, and we feel very helpless. No common officer will do. We have one of that kind in the building. What we want is a man of brains; he will need them."

A muffled sound at the other end—then a different voice asking some half-dozen comprehensive questions—which, having been answered to the best of the Curator's ability, were followed by the welcome assurance that a man on whose experience he could rely would be at the museum doors within five minutes.

With an air of relief Mr. Jewett stepped again into the court, and repelling with hasty gestures the importunities of the small group of men and women who had lacked the courage to follow the more adventurous ones upstairs, crossed to where the door-man stood on guard over the main entrance.

"Locked?" he asked.

"Yes, sir. Such were the orders. Didn't you give them?"

"No, but I should have done so, had I known. No one's to go out, and no one's to come in but the detective whom I am expecting any moment."

They had not long to wait. Before their suspense had reached fever-point, a tap was heard on the great door. It was opened, and a young man stepped in.

"Coast clear?" he sang out with a humorous twist of his jaw as he noted the Curator's evident chagrin at his meager and unsatisfactory appearance. "Oh, I'm not your man," he added as his eye ran over the whole place with a look which seemed to take in every detail in an instant. "Mr. Gryce is in the automobile. Wait till I help him up."

He was gone before the Curator could utter a word, only to reappear in a few minutes with a man in his wake whom the former at first blush thought to be as much past the age where experience makes for efficiency as the other seemed to be short of it.
