some sort of legal text-book on blackmail. We entered into conversation. He asked me if it was a subject I was interested in. I had to confess having had more than one occasion to look into it.â
âBut of course,â Hussey said cordially. âIt occurs in at least one of your tip-top stories. I remember them well.â
âNothing of the kind, Master. Pray desist from idle flattery. My interest was a consequence of what impertinent reviewers are disposed to call my other character. Not that blackmail â except of the very most genteel and velvet-glove sort â much turns up in the routine work of the FO. But during the war I had to branch out a little, and look into certain aspects of espionage.â
âYou certainly had to do that ,â Appleby said. Fabulous stories about Miss Barrace were coming back to him.
âFar more spies are created through blackmail than by the enticement of a comfortable numbered account in a Swiss bank. But that is commonplace to you, Sir John.â
âIt is. A pretty ghastly sort of commonplace, often enough.â
âOf course. Fear, not greed, is the mainspring of that whole futile industry. But we digress.â
âSo we do. And within ten minutes you will be calling upon me to get up and talk nonsense. So let us press on. Just why was this military character aggrieved by his text-book?â
âIt seemed to be because it was all about blackmailers being caught out. Just how the law can be exercised to cover and successfully send down even the most cunning of them. It wasnât in the least what the colonel â I am imagining him to be a colonel â was after.â
âOn the contrary,â Hussey prompted, âhe wanted tips on how to bring the thing off?â
âPrecisely. But he wasnât an unintelligent old rascal. He was aware of the value â call it the negative value â of cautionary tales. But he wanted, so to speak, the positive know-how.â
âWhich you would have been very well able to provide.â Hussey chuckled. âBut it wouldnât have been altogether moral to oblige him.â
âOne has oneâs professional obligations.â Alarmingly, Miss Barrace responded to Husseyâs chuckle with a deep and rumbling laugh. âI could hardly offer him even the small change of the subject.â
âWas he mad?â Appleby asked.
âIt must be evident that an element of eccentricity entered into his attitude.â Miss Barrace paused upon this eminently diplomatic reply. âWaiter, more brandy.â
âAnd then?â
âHe suggested that we might have further chats. It seemed not feasible, alas, that they should take place. So that is the end of my story. But I confess that I was left feeling curious about him.â
âA wholesome attitude,â Appleby said. âDid you, by any chance, exchange names?â
âCertainly not. He did, in fact, offer me his card. I tore it up on the platform without looking at it. It was either that, or taking an absurd story to the police.â
âSo it was.â Appleby was so impressed by this latest piece of information that quite a pause succeeded. âBy the way,â he said, âI am interested in some of the members of your club. Those two women at the far end of the table, for instance â the one in salmon-pink and the other in magenta. Who are they?â
âIâm afraid I donât know their names. They are recent accessions to our number, and I fear I am not quite keeping up. I think the salmon-pink one writes stories about archdeacons and prebendaries and precentors. Why should those in particularâ?â
âThey were introduced to me â or introduced themselves â in a confused sort of way. The magenta one was anxious that the salmon-pink one should tell me some interesting anecdote.â Appleby just perceptibly hesitated. âThere was to be a railway
