They were restrained by a policeman who had been called in from the street, and a passageway was hurriedly made for Chief Gleason and his companion.

Half a score of men and women had come from the adjoining rooms and offices and were gazing with mingled awe and consternation at the lifeless man on the floor. He was lying where he had fallen. A physician had been hurriedly summoned and was bending over him, engaged in making a superficial examination.

Chief Gleason started slightly when he beheld the upturned face of the dead man.

“Good heavens!” he muttered. “It’s Gaston Todd.”

Carter heard his muttered exclamation. Restraining him, at the same time furtively watching the physician, he said quietly:
