rudder. Use the stick against the turn.â
The Bishop succeeded in oozing in the general direction of the hangar, and accepted Miss Sackbutâs suggestion of a coffee. They drank it in the lounge. This was deserted except for a novice, a youth who was, it seemed, laboriously, and a little palely, preparing for his first cross-country flight as he bent over a table map in the corner.
âHe is flying to Marsham, ten miles away,â explained Miss Sackbut.
âWhy is he moving that piece of string round the map?â asked the Bishop curiously.
âHe is finding at what point of the compass Marsham is in relation to here.â
âReally! And then he merely has to fly by his compass on that course and he arrives there?â
âNo,â said Miss Sackbut; âhe must allow for deviation, according to a table placed on his compass.â
âOh!â answered the Bishop.
âHe has also to find out the wind strength and direction and work out a small vector triangle or use a little instrument which solves the problem automatically. The result will tell him the course he must steer.â
Dr. Marriott pressed his brow. âHow much more reasonable theology is! It sounds absurdly complicated. And does that bring him over Marsham aerodrome?â
Sally shook her head. âNo; because while he is up the wind will change and he will get hopelessly lost.â
âDear me! However will he reach Marsham?â
âThe chances are that he will not,â answered Miss Sackbut. âIf he is unscrupulous, he will fly to the railway line as soon as he is out of sight and follow it to Marsham, forgetting all about his compass. However, he is young and probably scrupulous, so he will wander all over England and finally land in a ploughed field to ask the inhabitants where he is. In getting off the ploughed field again he will hit a tree, and some time later we will send out a crash tender to bring the âplane in, if repairable, and himself, if conscious.â
âReally!â said the Bishop. âI donât think I shall like cross-country flying.â
âDonât worry,â answered the girl reassuringly. âYouâll be flying in a club machine, so I shall escort you. We take care never to damage a club machine. This bloke is flying in his own bus, so, of course, itâs all to the good if we get the job of repairing it.â
The Bishop shook a playful forefinger. âEither you are very heartless, Miss Sackbut, or else you are a little given to exaggeration.â
After sighing audibly and going out twice to look at the windsock, the youth left. Then Sally turned firmly to the Bishop. âIâm glad we are alone. Iâve wanted to talk to you seriously. I believe you have something on your mind. You were getting on quite nicely with your training until the last day or two, but now your mind doesnât seem on the job.â
Dr. Marriott felt a little defenceless before Sallyâs very direct methods of approach. Even his episcopacy seemed no barrier against it.
âThere is something on my mind,â admitted the Bishop at last. âSome very fishy things have turned up about Furnaceâs death, and Iâm reluctantly coming to the conclusion that I shall have to speak to the police about it. Thatâs not a thing I like doing.â
âGood lord!â exclaimed Sally, genuinely shocked. âYou, of all people! What on earth could you have heard? I am sure there is some mistake.â
âI do not think so,â he answered quietly. âLady Laura apparently had a letter from Furnace in which he told her he was going to put an end to things.â
Sally flushed. âItâs abominable! Laura is always saying that sort of thing. I donât believe it. Why didnât she mention it at the inquest? Itâs sheer publicity lust! Iâm sure she wrote the letter herself.â Sally panted with fury.
âI
