Heroes who have endured the heavy labour of reading to the end the story of The Unpresentable Appearance of Colonel Crane are aware that his achievement was the first of a series of feats counted impossible, like the quests of the Arthurian knights. For the purpose of this tale, in which the Colonel is but a secondary figure, it is enough to say that he was long known and respected, before his last escapade, as a respectable and retired military man in a residential part of Surrey, with a sunburnt complexion and an interest in savage mythology. As a fact, however, he had gathered the sunburn and the savage myths some time before he had managed to collect the respectability and the suburban residence. In his early youth he had been a traveller of the adventurous and even restless sort; and he only concerns this story because he was a member of a sort of club or clique of young men whose adventurousness verged on extravagance. They were all eccentrics of one kind or another, some professing extreme revolutionary and some extreme reactionary opinions, and some both. Among the latter may be classed Mr. Robert Owen Hood, the somewhat unlegal lawyer who is the hero of this tale. Robert Owen Hood was Crane’s most intimate and incongruous friend. Hood was from the first as sedentary as Crane was adventurous. Hood was to the end as casual as Crane was conventional. The prefix of Robert Owen was a relic of a vague revolutionary tradition in his family; but he inherited along with it a little money that allowed him to neglect the law and cultivate a taste for liberty and for drifting and dreaming in lost corners of the country, especially in the little hills between the Severn and the Thames. In the upper reaches of the latter river is an islet in which he loved especially to sit fishing, a shabby but not commonplace figure clad in grey, with a mane of rust-coloured hair and a long face with a large chin, rather like Napoleon. Beside him, on the occasion now in question, stood the striking contrast of his alert military friend in full travelling kit; being on the point of starting for one of his odysseys in the South Seas. “Well,” demanded the impatient traveller in a tone of remonstrance, “have you caught anything?” “You once asked me,” replied the angler placidly, “what I meant by calling you a materialist. That is what I meant by calling you a materialist.” “If one must be a materialist or a madman,” snorted the soldier, “give me materialism.”
