“From that to five; but even if the barge were delayed, and you got there first, which is very unlikely, I do not think that there would be the remotest chance of finding those villains on board. I reckon they would, as we agreed, launch the body overboard even before they got under way here, and they may either have landed again before the craft got under way, pretending that they had changed their minds, and then walked across to The Hague or to Haarlem, or have gone on with the barge for two hours, or even until daybreak. If by that time they were near Rotterdam, they may have stayed on board till they got there; if not, they may have landed, and finished the journey on foot, but they would certainly not have stopped on board after six or seven o'clock this morning. They would calculate that possibly we might get on their track at an early hour this morning, and set out in pursuit at once.

“However, it will doubtless be a satisfaction to you to be moving, and at least you will be able to overhaul the barge when you get to Rotterdam, and to hear what the boatmen say. The chances are they will not even have noticed that one of the men who came on board was missing. The men may very well have made up a long bundle, carried it on shore with them, or three of them may have carried a fourth ashore; and in the dark the bargemen were unlikely to have noticed that the number was less than when they came on board. However, it will be something for you to find out when and where the fellows landed.”

“Yes; I should certainly like to lay hands on them, though I am afraid we should find it very hard to prove that they had anything to do with this affair.”

“I think that also, Mr. Chetwynd. Morally, we may feel absolutely certain; but, unless the boatmen noticed that one of their number was missing when they landed, we have at present no evidence to connect them with it.”

“We will set out as soon as my other two men return. I told them to be back soon after twelve. I will write to you this evening from Rotterdam. Ah! here are the men.”

The door opened, and, to the stupefaction of the party, Mark Thorndyke entered the room.

“Good Heavens, Mark!” Dick exclaimed, springing forward and seizing his hand, “is it really you alive in the flesh? We had given you up for dead. We have been searching the town for you all night, and were just going to set out for Rotterdam in search of a barge on which we believed you were carried. Why, it seems almost a miracle!”

The two prize fighters also came forward, and shook hands with a pressure that would have made most men shrink.

“I am as glad, Mr. Thorndyke,” Gibbons said, “as if anyone had given me a thousand pounds. I have never quite given up hope, for, as I said to Mr. Chetwynd, if you got but a shadow of a chance, you would polish off those nigger fellows in no time; but I was afraid that they never would give you a chance. Well, I am glad, sir.”

“Mark, this is the Lieutenant of the watch here,” Dick said. “He has been most kind, and has himself headed the search that has been made for you all night. Now tell us all about it.”
