Tommy did not have a very happy evening, on the whole. But his mind worked slowly, and it was not until much later that the mad suspicion came upon him in full force.
Perhaps he is not to be blamed for his lack of immediate comprehension. The next few weeks were weeks of bewildered misery for him. It was not that the Princess’s attitude toward him had changed — she was just as tolerant of him as before, but M. Tibault was always there. He had a faculty of appearing as out of thin air — he walked, for all his height, as lightly as a butterfly — and Tommy grew to hate that faintest shuffle on the carpet that announced his presence as he had never hated the pound of the guns.
And then, hang it all, the man was so smooth, so infernally, unrufflably smooth! He was never out of temper, never embarrassed. He treated Tommy with the extreme of urbanity, and yet his eyes mocked, deep-down, and Tommy could do nothing. And, gradually, the Princess became more and more drawn to this stranger, in a soundless communion that found little need for speech — and that, too, Tommy saw and hated, and that, too, he could not mend.
He began to be haunted not only by M. Tibault in the flesh but by M. Tibault in the spirit. He slept badly, and when he slept, he dreamed — of M. Tibault, a man no longer, but a shadow, a specter, the limber ghost of an animal whose words came purringly between sharp little pointed teeth. There was certainly something odd about the whole shape of the fellow — his fluid ease, the mold of his head, even the cut of his fingernails — but just what it was escaped Tommy’s intensest cogitation. And when he did put his finger on it at length, at first he refused to believe.
A pair of petty incidents decided him, finally, against all reason. He had gone to Mrs. Dingle’s, one winter afternoon, hoping to find the Princess. She was out with his aunt, but was expected back for tea, and he wandered idly into the library to wait. He was just about to switch on the lights, for the library was always dark even in summer, when he heard a sound of light breathing that seemed to come from the leather couch in the corner. He approached it cautiously and dimly made out the form of M. Tibault, curled up on the couch, peacefully asleep.
The sight annoyed Tommy so that he swore under his breath and was back near the door on his way out, when the feeling we all know and hate, the feeling that eyes we cannot see are watching us, arrested him. He turned back — M. Tibault had not moved a muscle of his body to all appearance — but his eyes were open now. And those eyes were black and human no longer. They were green — Tommy could have sworn it — and he could have sworn that they had no bottom and gleamed like little emeralds in the dark. It only lasted a moment, for Tommy pressed the light-button automatically — and there was M. Tibault, his normal self, yawning a little but urbanely apologetic, but it gave Tommy time to think. Nor did what happened a trifle later increase his peace of mind.
They had lit a fire and were talking in front of it — by now, Tommy hated M. Tibault so thoroughly that he felt that odd yearning for his company that often occurs in such cases. M. Tibault was telling some anecdote and Tommy was hating him worse than ever for basking with such obvious enjoyment in the heat of the flames and the ripple of his own voice.
Then they heard the street-door open, and M. Tibault jumped up — and jumping, caught one sock on a sharp corner of the brass fire-rail and tore it open in a jagged flap. Tommy looked down mechanically at the tear — a second’s glance, but enough — for M. Tibault, for the first time in Tommy’s experience, lost his temper completely. He swore violently in some spitting, foreign tongue — his face distorted suddenly — he clapped his hand over his sock. Then, glaring furiously at Tommy, he fairly sprang from the room, and Tommy could hear him scaling the stairs in long, agile bounds.
Tommy sank into a chair, careless for once of the fact that he heard the Princess’s light laugh in the hall. He didn’t want to see the Princess. He didn’t want to see anybody. There had been something revealed when M. Tibault had torn that hole in his sock — and it was not the skin of a man. Tommy had caught a glimpse of — black plush. Black velvet. And then had come M. Tibault’s sudden explosion of fury. Good
He went to Professor Tatto that evening with a series of hypothetical questions, but as he did not dare confide his real suspicions to the Professor, the hypothetical answers he received served only to confuse him the more. Then he thought of Billy Strang. Billy was a good sort, and his mind had a turn for the bizarre. Billy might be able to help.
