Twelve persons are staying at a boarding house; the house is very carefully depicted but in order to stress the 'island' note, the rest of the town is casually shown as a secondary cross between natural mist and a primary cross between stage-properties and a real-estate agent's nightmare. As the author points out (indirectly) this method is somewhat allied to the cinema practice of showing the leading lady in her impossible dormitory years as glamorously different from a crowd of plain and fairly realistic schoolmates. One of the lodgers, a certain G. Abeson, art dealer, is found murdered in his room. The local police officer, who is described solely in terms of boots, rings up a London detective, asking him to come at once. Owing to a combination of mishaps (his car runs over an old woman and then he takes the wrong train) he is very long in arriving. In the meantime the inhabitants of the boarding house plus a chance passer-by, old Nosebag, who happened to be in the lobby when the crime was discovered, are thoroughly examined. All of them except the last named, a mild old gentleman with a white beard yellowish about the mouth, and a harmless passion for collecting snuffboxes, are more or less open to suspicion; and one of them, a fishy art-student, seems particularly so: half a dozen blood-stained handkerchiefs are found under his bed. Incidentally, it may be noted that in order to simplify and 'concentrate' things not a single servant or hotel employee is specifically mentioned and nobody bothers about their non-existence. Then, with a quick sliding motion, something in the story begins to shift (the detective, it must be remembered, is still on the way and G. Abeson's stiff corpse lying on the carpet). It gradually transpires that all the lodgers are in various ways connected with one another. The old lady in No.3 turns out to be the mother of the violinist in No.11. The novelist occupying the front bedroom is really the husband of the young lady in the third floor back. The fishy art-student is no less than this lady's brother. The solemn moonfaced person who is so very polite to everyone, happens to be butler to the crusty old colonel who, it appears, is the violinist's father. The gradual melting process continues through the art-student's being engaged to the fat little woman in No.5, and she is the old lady's daughter by a previous marriage. And when the amateur lawn-tennis champion in No.6 turns out to be the violinist's brother and the novelist their uncle and the old lady in No.3 the crusty old colonel's wife, then the numbers on the doors are quietly wiped out and the boarding-house motif is painlessly and smoothly replaced by that of a country-house, with all its natural implications. And here the tale takes on a strange beauty. The idea of time, which was made to look comic (detective losing his way… stranded somewhere in the night), now seems to curl up and fall asleep. Now the lives of the characters shine forth with a real and human significance and G. Abeson's sealed door is but that of a forgotten lumber room. A new plot, a new drama utterly unconnected with the opening of the story, which is thus thrust back into the region of dreams, seems to struggle for existence and break into light. But at the very moment when the reader feels quite safe in an atmosphere of pleasurable reality and the grace and glory of the author's prose seems to indicate some lofty and rich intention, there is a grotesque knocking at the door and the detective enters. We are again wallowing in a morass of parody. The detective, a shifty fellow, drops his h's, and this is meant to look as if it were meant to look quaint; for it is not a parody of the Sherlock Holmes vogue but a parody of the modern reaction from it. The lodgers are examined afresh. New clues are guessed at. Mild old Nosebag potters about, very absent-minded and harmless.
He had just dropped in to see if they had a spare room, he explains. The old gag of making the most innocent-looking person turn out to be the master-villain seems to be on the point of being exploited. The sleuth suddenly gets interested in snuffboxes. ''Ullo,' he says, ''ow about Hart?' Suddenly a policeman lumbers in, very red in the face and reports that the corpse has gone. The detective: 'What dy'a mean by gorn?' The policeman: 'Gone, Sir, the room is empty.' There was a moment of ridiculous suspense. 'I think,' said old Nosebag quietly, 'that I can explain.' Slowly and very carefully he removes his beard, his grey wig, his dark spectacles, and the face of G. Abeson is disclosed. 'You see,' says Mr Abeson with a self-deprecating smile, 'one dislikes being murdered.'
I have tried my best to show the workings of the book, at least some of its workings. Its charm, humour, and pathos can only be appreciated by direct reading. But for enlightenment of those who felt baffled by its habit of metamorphosis, or merely disgusted at finding something incompatible with the idea of a 'nice book' in the discovery of a book's being an utterly new one, I should like to point out that The Prismatic Bezel can be thoroughly enjoyed once it is understood that the heroes of the book are what can be loosely called 'methods. of composition'. It is as if a painter said: look, here I'm going to show you not the painting of a landscape, but the painting of different ways of painting a certain landscape, and I trust their harmonious fusion will disclose the landscape as I intend you to see it. In the first book Sebastian brought this experiment to a logical and satisfactory conclusion. By putting to the ad absurdum test this or that literary manner and then dismissing them one after the other, he deduced his own manner and fully exploited it in his next book Success. Here he seems to have passed from one plane to another rising a step higher, for, if his first novel is based on methods of literary composition – the second one deals mainly with the methods of human fate. With scientific precision in the classification, examination, and rejection of an immense amount of data (the accumulation of which is rendered possible by the fundamental assumption that an author is able to discover anything he may want to know about his characters, such capacity being limited only by the manner and purpose of his selection in so far as it ought to be not a haphazard jumble of worthless details but a definite and methodical quest), Sebastian Knight devotes the three hundred pages of Success to one of the most complicated researches that has ever been attempted by a writer. We are informed that a certain commercial traveller Percival Q at a certain stage of his life and in certain circumstances meets the girl, a conjuror's assistant, with whom he will be happy ever after. The meeting is or seems accidentaclass="underline" both happen to use the same car belonging to an amiable stranger on a day the buses went on strike. This is the formula: quite uninteresting if viewed as an actual happening, but becoming a source of remarkable mental enjoyment and excitement, when examined from a special angle. The author's task is to find out how this formula has been arrived at; and all the magic and force of his art are summoned in order to discover the exact way in which two lines of life were made to come into contact – the whole book indeed being but a glorious gamble on causalities or, if you prefer, the probing of the aetiological secret of aleatory occurrences. The odds seem unlimited. Several obvious lines of inquiry are followed with varying success. Working backwards the author finds out why the strike was fixed to take place that particular day and a certain politician's life-long predilection for the number nine is found to be at the root of the business. This leads us nowhere and the trail is abandoned (not without having given us the opportunity of witnessing a heated party debate). Another false scent is the stranger's car. We try to find out who he was and what caused him to pass at a given moment along a given street but when we do learn that he had passed there on his way to his office every week-day at the same time for the last years of his life, we are left none the wiser. Thus we forced to assume that the outward circumstances of meeting are not samples of fate's activity in regard to two, subjects but a given entity, a fixed point, of no causal import; and so, with a clear conscience we turn to the problem of why Q and the girl Anne of all people were made to come and stand side by side for a minute on the kerb at that particular spot. So the girl's line of fate is traced back for a time, then the man's, notes are compared, and then again both lives are followed up in turn.
