“Cases do seem so at first,” French returned, “but it’s wonderful how light gradually comes. It is almost impossible to commit a murder without leaving a clue, and if you think it over long enough you usually get it. But this, I admit, is a pretty tough proposition.” “Have you ever heard of anything like it before?” “So far it rather reminds me of a case investigated several years ago by my old friend Inspector Burnley—he’s retired now. A cask was sent from France to London which was found to contain the body of a young married French woman, and it turned out that her unfaithful husband had murdered her. He had in his study at the time a cask in which a group of statuary which he had just purchased had arrived, and he disposed of the body by packing it in the cask and sending it to England. It might well be that the same thing had happened in this case: that the murderer had purchased something which had arrived in this crate and that he had used the latter to get rid of the body. And as you can see, Doctor, that at once suggests a line of enquiry. What firm uses crates of this kind to despatch their goods and to whom were such crates sent recently? This is the sort of enquiry which gets us our results.” “That is very interesting. All the same, I’m glad it’s your job and not mine. I remember reading of that case you mention. The papers were absolutely full of it at the time. I thought it an extraordinary affair, almost like a novel.” “No doubt, but there is this difference between a novel and real life. In a novel the episodes are selected and the reader is told those which are interesting and which get results. In real life we try perhaps ten or twenty lines which lead nowhere before we strike the lucky one. And in each line we make perhaps hundreds of enquiries, whereas the novel describes one. It’s like any other job, you get results by pegging away. But it is interesting on the whole, and it has its compensations. Well, Doctor, I mustn’t keep you talking all night. I shall see you at the inquest to-morrow?” French’s gloomy prognostications were justified next day when the proceedings in the little courthouse came to an end. Nothing that was not already known came out and the coroner adjourned the enquiry for three weeks to enable the police to conclude their investigations. What those investigations were to consist of was the problem which confronted French when after lunch he sat down in the deserted smoking room of the little hotel to think matters out. In the first place, there was the body. What lines of enquiry did the body suggest?
