The Pit-Prop Syndicate, Freeman Wills Crofts [books to read for 12 year olds .txt] 📗

time reading up the subject so as to be able to talk on it without giving himself away. Then he set out on his mission.

In a couple of hours he returned.

“Got that all right,” he exclaimed, as he rejoined the inspector. “I went and saw the fellow; said I was going to start a distillery in the Ardennes where there was plenty of wood, and wanted to see his plant. He was very civil, and took me round and showed me everything. There is a shed there above the still furnaces with hoppers for the firewood to go down, and in it was standing the lorry⁠—the lorry, I saw our marks on the corner. It was loaded with firewood, and he explained that it would be emptied last thing before the day-shift left, so as to do the stills during the night. Well, I got a general look round the concern, and I found that the large tuns which contain the finished brandy were just at the back of the wall of the shed where the lorry was standing. So it is easy to see what happens. Evidently there is a pipe through the wall, and Raymond comes down at night and fills up the lorry.”

“And did you get his fingerprints?”

“Have ’em here.”

Locking the door of their private room, Laroche took from his pocket the sketch he had made.

“He held this up quite satisfactorily,” he went on, “and there should be good prints.”

Willis had meanwhile spread a newspaper on the table and taken from his suitcase a small bottle of powdered lampblack and a camel’s-hair brush. Laying the sketch on the newspaper he gently brushed some of the black powder over it, blowing off the surplus. To the satisfaction of both men, there showed up near the left bottom corner the distinct mark of a left thumb.

“Now the other side.”

Willis turned the paper and repeated the operation on the back. There he got prints of a left fore and second finger.

“Excellent, clear prints, those,” Willis commented, continuing: “And now I have something to tell you. While you were away I have been thinking over this thing, and I believe I’ve got an idea.”

Laroche looked interested, and the other went on slowly:

“There are two brandy-carrying lorries. Every night one of these lies at the distillery and the other at the clearing; one is being loaded and the other unloaded; and every day the two change places. Now we may take it that neither of those lorries is sent to any other place in the town, lest the brandy tanks might be discovered. For the same reason, they probably only make the one run mentioned per day. Is that right so far?”

“I should think so,” Laroche replied cautiously.

“Very well. Let us suppose these two lorries are Nos. 1 and 2. No. 1 goes to the distillery say every Monday, Wednesday and Friday, and returns on the other three days, while No. 2 does vice versa, one trip each day remember. And this goes on day after day, week after week, month after month. Now is it too much to assume that sooner or later someone is bound to notice this⁠—some worker at the clearing or the distillery, some policeman on his beat, some clerk at a window overlooking the route? And if anyone notices it will he not wonder why it always happens that these two lorries go to this one place and to no other, while the syndicate has six lorries altogether trading into the town? And if this observer should mention his discovery to someone who could put two and two together, suspicion might be aroused, investigation undertaken, and presently the syndicate is up a tree. Now do you see what I’m getting at?”

Laroche had been listening eagerly, and now he made a sudden gesture.

“But of course!” he cried delightedly. “The changing of the numbers!”

“The changing of the numbers,” Willis repeated. “At least, it looks like that to me. No. 1 does the Monday run to the distillery. They change the number plate, and No. 4 does it on Wednesday, while No. 1 runs to some other establishment, where it can be freely examined by anyone who is interested. How does it strike you?”

“You have got it. You have certainly got it.” Laroche was more enthusiastic than the inspector had before seen him. “It’s what you call a cute scheme, quite on par with the rest of the business. They didn’t leave much to chance, these! And yet it was this very precaution that gave them away.”

“No doubt, but that was an accident.”

“You can’t,” said the Frenchman sententiously, “make anything completely watertight.”

The next night they went out to the clearing, and as soon as it was dark once more entered the shed. There with more powder⁠—white this time⁠—they tested the tank lorry for fingermarks. As they had hoped, there were several on the secret fittings, among others a clear print of a left thumb on the rivet head of the spring.

A moment’s examination only was necessary. The prints were those of M. Pierre Raymond.

Once again Inspector Willis felt that he ought to have completed his case, and once again second thoughts showed him that he was as far away from that desired end as ever. He had been trying to find accomplices in the murder of Coburn, and by a curious perversity, instead of finding them he had bit by bit solved the mystery of the Pit-Prop Syndicate. He had shown, firstly, that they were smuggling brandy, and, secondly, how they were doing it. For that he would no doubt get a reward, but such was not his aim. What he wanted was to complete his own case and get the approval of his own superiors and bring promotion nearer. And in this he had failed.

For hours he pondered over the problem, then suddenly an idea which seemed promising flashed into his mind. He thought it over with the utmost care, and finally decided that in the absence of something better he must try it.
