The Superintendent seemed to find the other’s easy familiarity out of place.

“Good-evening, Inspector,” he answered with official abruptness. “You know Dr. Jordan?—Inspector French of the C.I.D. And this is Mr. Orchard, a clerk in this office, who discovered the crime.”

Inspector French greeted them genially. Behind his back at the Yard they called him “Soapy Joe” because of the reliance he placed on the suavity of his manners. “I know your name, of course, Doctor, but I don’t think we have ever met. Pleased to make your acquaintance, Mr. Orchard.” He subsided into a chair and went on: “Perhaps, Superintendent, you would just give me a hint of what this is all about before we go any further.”

The facts already learned were soon recited. French listened carefully, and annexing the constable’s notebook, complimented that worthy on his industry. “Well,” he beamed on them, “I suppose we’d better have a look round inside before Mr. Duke turns up.”

The party moved to the inner room, where French, his hands in his pockets, stood motionless for some minutes, surveying the scene.

“Nothing has been touched, of course?” he asked.

“Nothing. From what they tell me, both Mr. Orchard and Constable Alcorn have been most circumspect.”

“Excellent; then we may go ahead. Get your camera rigged, Giles, and take the usual photos. I think, gentlemen, we may wait in the other room until the photographs are taken. It won’t be long.”

Though French had tactfully bowed his companions out, he did not himself follow them, but kept prowling about the inner office, closely inspecting its contents, though touching nothing. In a few minutes the camera was ready, and a number of flashlight photographs were taken of the body, the safe, every part of both offices, and even the stairs and hall. In the amazing way in which tales of disaster travel, news of the crime had already leaked out, and a small crowd of the curious hung, open-mouthed, about the door.

Scarcely had the camera been put away, when the proceedings were interrupted by a fresh arrival. Hurried steps were heard ascending the stairs, and a tall, thin, extremely well-dressed old gentleman entered the room. Though evidently on the wrong side of sixty, he was still a handsome man, with strong, well-formed features, white hair, and a good carriage. Under normal circumstances he would have presented a dignified and kindly appearance, but now his face was drawn into an expression of horror and distress, and his hasty movements also betokened his anxiety. On seeing so many strangers, he hesitated. The Inspector stepped forward.
