So Mike laughed perfunctorily, took back the envelope with the five pounds, accepted a ginger beer and a plateful of biscuits, and rode off on his return journey. * * * * * Mention has been made above of the difference which exists between getting into an inn after lockup and into a private house. Mike was to find this out for himself. His first act on arriving at Sedleigh was to replace his bicycle in the shed. This he accomplished with success. It was pitch-dark in the shed, and as he wheeled his machine in, his foot touched something on the floor. Without waiting to discover what this might be, he leaned his bicycle against the wall, went out, and locked the door, after which he ran across to Outwood's. Fortune had favored his undertaking by decreeing that a stout drainpipe should pass up the wall within a few inches of his and Psmith's study. On the first day of term, it may be remembered he had wrenched away the wooden bar which bisected the window frame, thus rendering exit and entrance almost as simple as they had been for Wyatt during Mike's first term at Wrykyn. He proceeded to scale this water pipe. He had got about halfway up when a voice from somewhere below cried, "Who's that?" 16 PURSUIT These things are Life's Little Difficulties. One can never tell precisely how one will act in a sudden emergency. The right thing for Mike to have done at this crisis was to have ignored the voice, carried on up the water pipe, and through the study window, and gone to bed. It was extremely unlikely that anybody could have recognized him at night against the dark background of the house. The position then would have been that somebody in Mr. Outwood's house had been seen breaking in after lights-out; but it would have been very difficult for the authorities to have narrowed the search down any further than that. There were thirty-four boys in Outwood's, of whom about fourteen were much the same size and build as Mike. The suddenness, however, of the call caused Mike to lose his head. He made the strategic error of sliding rapidly down the pipe, and running. There were two gates to Mr. Outwood's front garden. The drive ran in a semicircle, of which the house was the center. It was from the right-hand gate, nearest to Mr. Downing's house, that the voice had come, and, as Mike came to the ground, he saw a stout figure galloping toward him from that direction. He bolted like a rabbit for the other gate. As he did so, his pursuer again gave tongue. "Oo-oo-oo yer!" was the exact remark. Whereby Mike recognized him as the school sergeant. "Oo-oo-oo yer!" was that militant gentleman's habitual way of beginning a conversation.
