In his leisure from these flights Mr. Fargus was intensely absorbed in chess, in the game of Patience, and in the solution of acrostics. Sabre was also fond of chess and attracted by acrostics; and regular evenings of every week were spent by the two in unriddling the problems set in the chess and acrostic columns of journals taken in for the purpose. They would sit for hours solemnly staring at one another, puffing at pipes, in quest of a hidden word beginning with one letter and ending with another, or in search of the two master moves that alone would produce Mate. (It was a point of honour not to work out chess problems on a board but to do them in your head.) Likewise for hours the two in games of chess and in competitive Patience, one against the other, to see who would come out first. And to all these mental exercises--chess, acrostics and Patience--an added interest was given by Mr. Fargus's presentation of them as illustrative of his theory of life. Mr. Fargus's theory of life was that everybody was placed in life to fulfil a divine purpose and invested with the power to fulfil it. "No, no, it's not fatalism," Mr. Fargus used to say. "Not predestination. It's just exactly like a chess problem or an acrostic. The Creator sets it. He knows the solution, the answer. You've got to work it out. It's all keyed for you just as the final move in chess or the final discovery in an acrostic is keyed up to right from the start." And on this argument Mr. Fargus introduced Sabre to the great entertainment in "working back" when a game of Patience failed to come out or after a defeat in chess. You worked back to the immense satisfaction of finding the precise point at which you went wrong. Up to that point you had followed the keyed path; precisely there you missed it. "Tremendous, eh?" Mr. Fargus used to say. "Terrific. If you hadn't done that you'd have got it. That one move, all that way back, was calamity. Calamity! What a word!" And they would stare bemused eyes upon one another. "You put that into life," Mr. Fargus used to say. "Imagine if every life, at death, was worked back, and where it went wrong, where it made its calamity, and the date, put on the tombstone. Eh? What a record! Who'd dare walk through a churchyard?" Sabre's objection was, "Of course no one would ever know. Suppose your idea's correct, who's to say what a man's purpose in life was, let alone whether he'd fulfilled it? How can you work towards a purpose if you don't know what it is?" Then little old Mr. Fargus would grow intense. "Why, Sabre, that's just where you are with an acrostic or in chess. How can you work out the solution when you don't know what the solution is?" "Yes, but you know there is a solution." Mr. Fargus's eyes would shine. "Well, there you are! And you know that in life there is a purpose."
