At least, the latter seemed grateful to receive whatever was given to him, and his general manner became decidedly more possible. There seemed less chance now of a drastic relapse. The Doctor had locked the door of the surgery. It would be embarrassing to be discovered in such circumstances, and Mrs. Masters might faint with horror at the sight of the empty tins and bottles and the gorging visitor. It was symptomatic of the Doctor's frame of mind that even now the one thing he dreaded more than anything else was the intrusion of a curious world into this monstrous proceeding. He had been forced into accepting the evidence of his own eyes, but there still remained in him a strong desire to hush up the affair, to protect the world at large from so fierce a shock to its established ideas. The surgery was a low-pitched apartment, and it was approached by patients from the outside by way of the area steps. One door communicated with the dark passage that led to the kitchen quarters, and the other opened directly upon the area. A double row of shelves, well stocked with bottles, occupied the centre of the room and divided it into two halves. Beneath the window stood the Doctor's neat bureau, and to the left of this was a low couch beside the wall. A shaded lamp on the desk was sufficient to light the room for ordinary purposes; but there was a gas burner near the further door, which had to be lit when the Doctor was engaged upon some very close examination or had to perform a slight operation. Directly underneath this burner there stood an arm-chair of ample proportions, and it was here that the Clockwork man had seated himself at the beginning of his orgy. The Doctor sat upon the couch, with his hands limply hanging between his knees. He was conscious of perspiration, but made no attempt to wipe his forehead. His heart was knocking hard against his ribs, and occasionally missing a beat. He noticed this fact also, but it caused him little concern. Now and again he looked swiftly at the Clockwork man and studied his extraordinary method of mastication, the rapid vibratory movement of the jaws, the apparent absence of any kind of voluntary effort.
