‘The Moon River runs through a gorge beyond the homestead. Flossie sometimes walked up there in the evening. She said it helped her, God save the mark, to think. When, finally, the police were brought in, they fastened like limpets upon this bit of information and, after hunting about the cliff for hours at a time, waited for poor Flossie to turn up ten miles downstream where there is a backwash or something. They were still waiting when the foreman at Riven’s wool store made his unspeakable discovery. By that time the trail was cold. The wool-shed had been cleaned out, the shearers had moved on, heavy rains had fallen, nobody could remember with any degree of accuracy the events of the fatal evening. Your colleagues of our inspired detective force are still giving an unconvincing impersonation of hounds with nose to ground. They return at intervals and ask us the same questions all over again. That’s all, really. Or is it?’
‘It’s a very neat resumé, at all events,’ said Alleyn. ‘But I’m afraid I shall have to imitate my detested colleagues and ask a great many questions.’
‘I am resigned.’
‘Good. First, then, is your household unchanged since Mrs Rubrick’s death?’
‘Arthur died of heart trouble three months after she disappeared. We’ve acquired a housekeeper, an elderly cousin of Arthur’s called Mrs Aceworthy, who quarrels with the outside men and preserves the proprieties between the two girls, Douglas and myself. Otherwise there’s been no change.’
‘Yourself,’ said Alleyn, counting, ‘Captain Grace, who is Mrs Rubrick’s nephew, Miss Ursula Harme, her ward, and Miss Terence Lynne, her secretary. What about servants?’
‘A cook, Mrs Duck, if you’ll believe me, who has been at Mount Moon for fifteen years, and a manservant, Markins, whom Flossie acquired in a fashion to be related hereafter. He’s a phenomenon. Menservants are practically non-existent in this country.’
‘And what about the outside staff at that time? As far as I can remember there was Mr Thomas Johns, the manager, his wife and his son, Cliff; an odd man – is rouseabout the right word? – called Albert Black, three shepherds, five visiting shearers, a wool-classer, three boys, two gardeners, a cowman, and a station cook. Right?’
‘Correct, even to the cowman. I need tell you nothing, I see.’
‘On the night of the disappearance, the shearers, the gardeners, the boys, the station cook, the sorter, the shepherds and the cowman were all at an entertainment held some fifteen miles away?’
‘Dance at the Social Hall, Lakeside. It’s across the flat on the main road,’ said Fabian, jerking his head at the vast emptiness of the plateau. ‘Arthur let them take the station lorry. We had more petrol in those days.’
‘That leaves the house-party, the Johns family, Mrs Duck, the rouseabout, and Markins?’
‘Exactly.’
Alleyn clasped his long hands round his knee and turned to his companion. ‘Now, Mr Losse,’ he said tranquilly, ‘will you tell me exactly why you asked me to come?’
Fabian beat his open palm against the driving-wheel. ‘I told you in my letter. I’m living in a nightmare. Look at the place. Our nearest neighbour’s ten miles up the road. What do you think it feels like? And when in January shearing came round again, there were the same men, the same routine, the same long evenings, the same smell of lavender and honeysuckle and oily wool. We’re crutching now and getting it all over again. The shearers talk about it. They stop when any of us come up, but every smoke-oh and every time they knock off it’s “the murder”. What a beastly soft noise the word makes. They’re using the wool-press, of course. The other evening I caught one of the boys that sweep up the crutchings squatting in the press while the other packed a fleece round him. Experimenting. God, I gave them a fright, the little bastards.’ He swung round and confronted Alleyn. ‘We don’t talk about it. We’ve clamped down on it now for six months. That’s bad for all of us. It’s interfering with my work. I’m doing nothing.’
‘Your work. Yes, I was coming to that.’
‘I suppose the police told you.’
‘I’d heard already at army headquarters. It overlaps my job out here.’
‘I suppose so,’ said Fabian. ‘Yes, of course.’
‘You realize, don’t you, that I’m out here on a specific job. I’m here to investigate the possible leakage of information to the enemy. My peace-time job as a CID man has nothing to do with my present employment. But for the suggestion that Mrs Rubrick’s death may have some connection with our particular problem I should not have come. It’s with the knowledge and at the invitation of my colleagues that I’m here.’
‘I got a rise with my bait then,’ said Fabian. ‘What did you think of my brain-child?’
‘They showed me the blueprints. Beyond me, of course. I’m not a gunner. But I could at least appreciate its importance and also the extreme necessity of keeping your work secret. It is from that point of view, I believe, that the suggestion of espionage has cropped up?’
‘Yes. To my mind it’s an absurd suggestion. We work in a room that’s locked when we’re not in it, and the papers and gear – any of them that matter – are always shut up in a safe.’
‘We?’
‘Douglas Grace has worked with me. He’s done the practical stuff. My side is purely theoretical. I was at Home when war broke out and took an inglorious part in the now mercifully forgotten Norwegian campaign, I picked up rheumatic fever but, with an extraordinarily bad sense of timing, got back into active service just in time to get a crack on the head at Dunkirk.’ Fabian paused for a moment as if he had been about to say something further but now changed his mind. ‘Ah, well,’ he said. ‘There it was. Later on still, when I was supposed to be fairly fit, they put me into a special show in England. That’s when I got the germ of the idea. I cracked up again rather thoroughly and they kicked me out for good. While I was still too groggy to defend myself, Flossie, who was Home on a visit, bore down upon me and conceived the idea of bringing her poor English nephew-in-law back with her to recuperate in this country. She said she was used to looking after invalids, meaning poor old Arthur’s endocarditis. I started messing about with my notion soon after I got here.’
‘And her own nephew? Captain Grace?’
‘He was actually taking an engineering course at Heidelberg in 1939 but he left on the advice of some of his German friends and returned to England. May I take this opportunity of assuring you that Douglas is not in the pay of Hitler or any of his myrmidons, a belief ardently nursed, I feel sure, by Sub-Inspector Jackson. He enlisted when he got to England, was transferred to a New Zealand unit, and was subsequently pinked in the bottom by the Luftwaffe in Greece. Flossie hauled him in as soon as he was demobilized. He used to work here as a cadet in his school holidays. He’s always been good with his hands. He’d got a small precision lathe and some useful instruments. I pulled him in. It’s Douglas who’s got this bee in his bonnet. He will insist that in some fantastic way his Auntie Flossie’s death is mixed up with our egg-beater, which is what we ambiguously call our magnetic fuse.’
‘Why does he think so?’
Fabian did not answer.
‘Has he any data –’ Alleyn began.
‘Look here, sir,’ said Fabian abruptly. ‘I’ve got a notion for your visit. It may not appeal to you. In fact, you may dismiss it as the purest tripe, but here it is. You’re full of official information
