The villa of Mr. Simon Rattar was now half seen beyond the curving end of the belt that bounded the drive. It was dim against the night sky, and the garden was dimmer still. Carrington kept on the grass, following the outside of the trees, and then again plunged into them when they curved round at the top of the drive. Pushing quietly through, he reached the other side, and there his expedition in search of fresh air seemed to have found its goal, for he leaned his back against a tree trunk, folded his arms, and waited.

He was looking obliquely across a sweep of gravel, with the whole front of the house full in view. A ray came from the fanlight over the front door and a faint radiance escaped through the slats of the library blinds, but otherwise the villa was a lump of darkness in the dark.

One minute after another passed without event and with scarcely even the faintest sound. Then, all at once, a little touch of breeze sprang up and sighed overhead through the tree tops, and from that time on, there was an alternation of utter silence with the sough of branches gently stirred.

From a church tower in the town came the stroke of a clock. Carrington counted nine and his eyes were riveted on the front door now. Barely two more minutes passed before it opened quietly; a figure appeared for an instant in the light of the hall, and then, as quietly, the door closed again. There was a lull at the moment, but Carrington could hear not a sound. The figure must be standing very still on the doorstep, listening—evidently listening. And then the thickset form of Simon Rattar appeared dimly on the gravel, crossing to the lawn beyond. The pebbles crunched a little, but not very much. He seemed to be walking warily, and when he reached the further side he stood still again and Carrington could see his head moving, as though he were looking all round him through the night.

But now the figure was moving again, coming this time straight for the head of the belt of trees. Carrington had drawn on a pair of dark gloves, and he raised his arm to cover the lower part of his face, looking over it through the branches, and facing the silent owner of the garden, till there were hardly three paces between them, the one on the lawn, the other in the heart of the plantation.

And then when Simon was exactly opposite, he stopped dead. Carrington's other hand slipped noiselessly into the pocket where he had dropped that little article, but otherwise he never moved a muscle and he breathed very gently. The man on the turf seemed to be doing something with his hands, but what, it was impossible to say. The hands would move into his pocket and then out again, till quite three or four minutes had passed, and then came a sudden flash of light. Carrington's right hand moved halfway out of his pocket and then was stayed, for by the light of the match he saw a very singular sight.

Simon Rattar was not looking at him. His eyes were focussed just before his nose where the bowl of a pipe was beginning to glow. Carrington could hear the lips gently sucking, and then the aroma of tobacco came in a strong wave through the trees. Finally the match went out, and the glowing pipe began to move slowly along the turf, keeping close to the shelter of the trees.

For a space Carrington stood petrified with wonder, and then, very carefully and quite silently, he worked his way through the trees out on to the turf, and at once fell on his hands and knees. Had any one been there to see, they would have beheld for the next five minutes a strange procession of two slowly moving along the edge of the plantation; a thickset man in front smoking a pipe and something like a great gorilla stalking him from behind. This procession skirted the plantation nearly down to the gate; then it turned at right angles, following the line of trees that bordered the wall between the garden and the road; and then again at right angles when it had reached the further corner of Mr. Rattar's demesne. Simon was now in a secluded path with shrubs on either hand, and instead of continuing his tour, he turned at the end of this path and paced slowly back again. And seeing this, the ape behind him squatted in the shadow of a laurel and waited.

A steady breeze was now blowing and the trees were sighing continuously. The sky at the same time cleared, and more and more stars came out till the eyes of the man behind the bush could follow the moving man from end to end of the path. The wind made the pipe smoke quickly, and presently a shower of sparks showed that it was being emptied, and in a minute or two another match flashed and a second pipe glowed faintly.
