“What if they get into a carriage that’s already nearly full?” suggested the dubious Smith.

“They won’t do that,” replied Jenkins with a laugh. “It seems to be against the laws of human nature to do that. As long as there are empty carriages in a train, so long will men and women pass every carriage that has a soul in it, until they find an empty one for themselves. We have nothing to do but follow them, and, when they have pitched on a carriage, get in after them, and fill it up, so we shall have it all to ourselves.”

“Come along, then; it’s time to stop talking and to act,” said Thomson, testily, as he moved towards the carriages.

That even the wisest of men (in his own conceit) may make mistakes now and then is a fact which was beautifully illustrated on this occasion. We may here let the reader into the secret of Jenkins, Smith, and Thomson. They were men who lived by their wits. They had ascertained that a partner of a certain house that dealt in jewellery meant to return to London by that particular train, with a quantity of valuables that were worth running some risk for. On the journey there was one stoppage quite close to London. The run immediately before that was a clear one of seventy-five miles without a halt, at full express speed, which would afford them ample opportunity for their purpose, while the slowing of the train on approaching the stopping place would give them opportunity and time to leap out and make off with their booty. They had been told that their intended victim was a stout resolute man, but that would avail nothing against numbers.

Having obtained all requisite information they had proceeded thus far with their villainous design, apparently with success. But at this point a hitch occurred, though they knew it not. They had not taken sufficiently into account the fact that black leather bags may be both stout and peculiar, and in some degree similar without being identical. Hence Smith and Jenkins in their self-confidence had settled, as we have seen, that Captain Lee was “their man,” whereas their man was comfortably seated in another carriage, and by his side the coveted bag, which was similar in some points to that of the captain, but different in size and in several small details.

Following the wrong scent, therefore, with wonted pertinacity, the three men sauntered behind Captain Lee and Edwin, who, true to the “laws” with which Jenkins had credited human nature, passed one carriage after another until they found an empty one.

“Here is one, Gurwood,” said the captain.

He was about to step into it, when he observed Mrs Durby sitting in the next compartment.

“Hallo! nurse,” he exclaimed, getting in and sitting down opposite to her; “why, surely it wasn’t you, was it, that had such a narrow escape?”

“Indeed it was, Capting Lee,” replied Mrs Durby in a half whimper, for albeit a woman of strong character, she was not proof against such rough treatment as she had experienced that day.
