"On May 1st the boy arrived, that being the beginning of the summer term. He was a charming youth, and he soon fell into our ways. I may tell you -- I trust that I am not indiscreet, but half-confidences are absurd in such a case -- that he was not entirely happy at home. It is an open secret that the Duke's married life had not been a peaceful one, and the matter had ended in a separation by mutual consent, the Duchess taking up her residence in the South of France. This had occurred very shortly before, and the boy's sympathies are known to have been strongly with his mother. He moped after her departure from Holdernesse Hall, and it was for this reason that the Duke desired to send him to my establishment. In a fortnight the boy was quite at home with us, and was apparently absolutely happy.
"He was last seen on the night of May 13th -- that is, the night of last Monday. His room was on the second floor, and was approached through another larger room in which two boys were sleeping. These boys saw and heard nothing, so that it is certain that young Saltire did not pass out that way. His window was open, and there is a stout ivy plant leading to the ground. We could trace no footmarks below, but it is sure that this is the only possible exit.
"His absence was discovered at seven o'clock on Tuesday morning. His bed had been slept in. He had dressed himself fully before going off in his usual school suit of black Eton jacket and dark grey trousers. There were no signs that anyone had entered the room, and it is quite certain that anything in the nature of cries, or a struggle, would have been heard, since Caunter, the elder boy in the inner room, is a very light sleeper.
"When Lord Saltire's disappearance was discovered I at once called a roll of the whole establishment, boys, masters, and servants. It was then that we ascertained that Lord Saltire had not been alone in his flight. Heidegger, the German master, was missing. His room was on the second floor, at the farther end of the building, facing the same way as Lord Saltire's. His bed had also been slept in; but he had apparently gone away partly dressed, since his shirt and socks were lying on the floor. He had undoubtedly let himself down by the ivy, for we could see the marks of his feet where he had landed on the lawn. His bicycle was kept in a small shed beside this lawn, and it also was gone.
"He had been with me for two years, and came with the best references; but he was a silent, morose man, not very popular either with masters or boys. No trace could be found of the fugitives, and now on Thursday morning we are as ignorant as we were on Tuesday. Inquiry was, of course, made at once at Holdernesse Hall. It is only a few miles away, and we imagined that in some sudden attack of home-sickness he had gone back to his father; but nothing had been heard of him. The Duke is greatly agitated -- and as to me, you have seen yourselves the state of nervous prostration to which the suspense and the responsibility have reduced me. Mr. Holmes, if ever you put forward your full powers, I implore you to do so now, for never in your life could you have a case which is more worthy of them."
Sherlock Holmes had listened with the utmost intentness to the statement of the unhappy schoolmaster. His drawn brows and the deep furrow between them showed that he needed no exhortation to concentrate all his attention upon a problem which, apart from the tremendous interests involved, must appeal so directly to his love of the complex and the unusual. He now drew out his note-book and jotted down one or two memoranda.
