We compared notes, and Hewitt laughed heartily. “The appearance of Emma Trennatt at Geldard’s office this morning is explained,” he said. “She went first with a message from Geldard to Mrs. Geldard at Camberwell, explaining his absence and imploring her not to talk of it or make a disturbance. Mrs. Geldard had gone off to town, and Emma Trennatt was told that she had gone to Geldard’s office. There she went, and then we first saw her. She found nobody at the office, and after a minute or two of irresolution returned to Camberwell, and then succeeded in delivering her message, as you saw. Mrs. Geldard is apparently satisfied with her husband’s explanation. But I’m afraid the revenue officers won’t approve of it.” “The revenue officers?” “Yes. It’s a case of illicit distilling--and a big case, I fancy. I’ve wired to Somerset House, and no doubt men are on their way here now. But Mrs. Geldard’s up at the house, so we’d better hurry up to the police station and have a few sent from there. Come along. The whole thing’s very clever, and a most uncommonly big thing. If I know all about it--and I think I do--Geldard and his partners have been turning out untaxed spirit by the hundred gallons for a long time past. Geldard is the practical man, the engineer, and probably erected the whole apparatus himself in that house on the hill. The spirit is brought down by a pipe laid a very little way under the garden surface, and carried into one of the irrigation stand-pipes in the nursery ground. There’s a quiet little hole behind the pipe with a couple of stop-cocks--one to shut off the water when necessary, the other to do the same with the spirit. When the stopcocks are right you just turn the tap at the top of the pipe and you get water or whisky, as the case may be. Fuller, the man up at the house, attends to the still, with such assistance as the deaf old woman can give him. Trennatt, down below, draws off the liquor ready to be carried away. These two keep up an ostentatious appearance of being at unending feud to blind suspicion. Our as yet ungreeted friend Geldard, guiding spirit of the whole thing, comes disguised as a carter with an apparent cart-load of linoleum, and carries away the manufactured stuff. In the pleasing language of Geldard and Co., ‘smoke,’ as alluded to in the note you saw, means whisky. Something has been wrong with the apparatus lately, and it has been leaking badly. Geldard has been at work on it, patching, but ineffectually. ‘What you did was no good’ said the charming Emma in the note, as you will remember. ‘Uncle was anxious.’ And justifiably so, because not only does a leak of spirit mean a waste, but it means a smell, which some sharp revenue man might sniff. Moreover, if there is a leak, the liquid runs somewhere at random, and with any sudden increase in volume attention might easily be attracted. It was so bad that ‘F.’ (Fuller) thought Geldard must light another pipe (start another
