Immediately underneath was another window, opening on a leaded balcony over the bow-window in the drawing-room. To shift his bedstead with the least possible noise, to tie a sheet to it, and to slide down the sheet till he had but a few feet to drop into the balcony, was the work of a very few minutes to one as excitedly determined as Pocket had become on finding himself a prisoner. Thought they would lock him in, did they? They would just find out their mistake! It was exactly the same mood in which he had scaled the upright palings in defiance of the policeman who said he might not sleep in the Park.

The balcony window was open, the room within empty. It was obviously Baumgartner’s bedroom. There was a camp bedstead worthy of an old campaigner, a large roll-top desk, and a waste-paper basket which argued either a voluminous correspondence or imperfect domestic service; it would have furnished scent for no short paper-chase. Otherwise the room was tidy enough, and so eloquent of Baumgartner himself, in its uncompromising severity, that Pocket breathed more freely on the landing. And in the hall he felt absolutely safe, for he had gained it without the creaking of a stair, and there on the pegs hung his hat, but neither the cloak nor the weird wide-awake affected by his host.

Baumgartner out. That was a bit of luck; and it was just like Pocket to lose a moment in taking advantage of it; but the truth was that he had made an interesting discovery. It was in that house the piano was being played. He heard it through the drawing-room door; he had heard it on the balcony up above; it had never stopped once, so silent had he been. It was that Phillida, with the large dark eyes, and she was playing something that Lettice sometimes played, and very nearly, though naturally not quite, as well. Pocket would have said that it was Mendelssohn, or Chopin, “or something,” for his love of music was greater than his knowledge. But it was not exactly the music that detained him; he was thinking more of the musician, who had shown him kindness, after all. It would be only decent to thank her before he went, and the doctor himself through his niece. If she knew he had been locked in, and he had to tell her how he had made his escape and yet not a sound—well, she would not think the less of him at all events, and so they would part for ever. Or perhaps not for ever! The juvenile instinct for romance was not to be stifled at such a stimulating moment. The girl would be sorry for him when she knew all; she might know enough to be sorry for him as it was; in any case it was the game to say goodbye.

The girl sprang from the music-stool in extraordinary excitement. Her large eyes were larger than ever, as it were with fear, and yet they blazed at the intruder. Pocket could not understand it, unless she already knew the truth.

“I’m so sorry for starting you,” he apologised. “I just came in to say goodbye.”

And he held out a hand which she never seemed to see.

“To say goodbye!” she gasped.

“Yes, I’ve got to go. I’m afraid the doctor’s out?”

“Yes, he is. Won’t you wait?”

“I’m afraid I can’t.”
