Paul Harley, although the fact was unknown to the general public, occupied something of the position of an unofficial field marshal of the forces arrayed against evildoers. Throughout the war he had undertaken confidential work of the highest importance, especially in regard to the Near East, with which he was intimately acquainted. A member of the English bar, and the last court of appeal to which Home Office and Foreign Office alike came in troubled times, the brass plate upon the door of his unassuming premises in Chancery Lane conveyed little or nothing to the uninitiated. The man himself, with his tropical bronze and air of eager vitality, must have told the most careless observer that he stood in the presence of an extraordinary personality. He was slightly gray at the temples in these days, but young in mind and body, physically fit, and possessed of an intellectual keenness which had forced recognition from two hemispheres. His office was part of an old city residence, and his chambers adjoined his workroom, so that now, noting that his table clock registered the hour of six, he pressed a bell which summoned Innes, his confidential secretary. “Well, Innes,” said Harley, looking around, “another uneventful day.” “Very uneventful, Mr. Harley. About a month of this and you will have to resume practice at the bar.” Paul Harley laughed. “Not a bit likely, Innes,” he replied. “No more briefs for me. I shall retire to Norfolk and devote my declining years to fishing.” “I don’t know that fishing would entirely satisfy me,” said Innes. “It would more than satisfy me,” returned Harley. “But every man to his own ambition. Well, there is no occasion to wait; you might as well get along. But what’s that you’ve got in your hand?” “Well,” replied Innes, laying a card upon the table, “I was just coming in with it when you rang.” Paul Harley glanced at the card. “Sir Charles Abingdon,” he read aloud, staring reflectively at his secretary. “That is the osteologist?” “Yes,” answered Innes, “but I fancy he has retired from practice.” “Ah,” murmured Harley, “I wonder what he wants. I suppose I had better see him, as I fancy that he and I met casually some years ago in India. Ask him to come in, will you?” Innes retiring, there presently entered a distinguished-looking, elderly gentleman upon whose florid face rested an expression not unlike that of embarrassment. “Mr. Harley,” he began, “I feel somewhat ill at ease in encroaching upon your time, for I am by no means sure that my case comes within your particular province.” “Sit down, Sir Charles,” said Harley with quiet geniality. “Officially, my working day is ended; but if nothing comes of your visit beyond a chat it will have been very welcome. Calcutta, was it not, where we last met?”
