Wilfrid could have told Vardon so, too, but he held his tongue. It was singular that circumstances should have placed him in a position to prove the truth of the negro's words. It was strange, too, that the African should have been so eager to conceal his movements on the previous evening. Vardon listened impatiently.

"But that is all nonsense," he said. "You don't seem to understand what a serious position you are in. A man in hospital is badly hurt. He declares that he gave you no provocation whatever, and he has a score of witnesses to prove that your attack was brutal and uncalled for. If you can't prove beyond a doubt that you were elsewhere last night, you will be committed to take your trial at the Assizes, and at the very least you will not get off under two years' imprisonment. In any case, the alibi will be a difficult one to establish; all the more because negroes of your size are not to be found wandering about in every country road. Now, are you alone here? Have you any fellow-countrymen in the circus?"

"Two," the Ethiopian replied. "Only two besides myself. But the others are men just about the usual size, and they were in the stable all the time."

"That is rather awkward," Vardon murmured. "Still, as we are not very far from Chatham, where there are sailors of all kinds, it is possible that one of your own countrymen about your own build might have been coming along at the time. As those fellows were all more or less intoxicated some insulting remarks might have been made. Still, it is in your own hands. And unless Mr. Gordon comes forward and speaks for you, your position is by no means a safe one."

The negro began to comprehend now. He glanced uneasily at the face of his lawyer.

"I'll go and see, sir," he said.

He came back presently with a large, florid-looking individual, loudly dressed and smoking an exceedingly strong cigar. The pattern of his clothing proclaimed the man, as also did his white bowler hat, which was jauntily cocked on the side of his head. Wilfrid hardly needed to look at the man to recognize him as the individual who had been driving the dogcart near Maldon Grange the night before. Indeed, Wilfrid would have been surprised to see anybody else.

"This is Mr. Gordon, sir," the negro said.

"Quite at your disposal," the proprietor of the circus said floridly. "This poor chap of mine seems to have got himself into trouble. But whatever those drunken scamps say, Sam is innocent, for the simple reason he wasn't here last night. He was out on important business for me; in fact, we were out together. It is rather a nuisance because I don't want our errand to become public property, as it had to do with two of my troupe who had absconded. We have only been in England two or three days and within twenty-four hours those fellows took French leave. A great nuisance it is, too, because they were down for a turn which would have packed the circus for the next month to come. And I give you my word for it, I picked up those two fellows at Marseilles where they were absolutely starving. And after costing me thirty or forty pounds between them, they go off and leave me in the lurch like this. Still, I can speak plainly enough now because they have vanished again. I thought I had them safe and sound last night, but those chaps are slippery as eels. I am not going to trouble any more about them and I'll just cut my loss and let them slide. And now, sir, I am prepared to go into the witness-box and take my oath that Sam here was with me in my cart ten miles from Castlebridge at the moment when the assault was committed. Is that good enough?"

Wilfrid could have testified the same had he chosen to do so, but it was not for him to speak then. He had learnt a great deal the last ten minutes. He had learnt that the two mysterious men who had caused such commotion at Maldon Grange were foreigners who had been members of the circus troupe. It was obvious, too, why they had signed an agreement with Gordon. They had been eager to come to England, and for that reason had jumped at Gordon's offer. Perhaps they had ascertained that, sooner or later, the wanderings of the circus would bring them in more or less close contact with Samuel Flower. An absence from the circus the night before was easily explained. But after being brought back again to Castlebridge why had they disappeared in this extraordinary fashion? Beyond all doubt they had made up their minds to murder Samuel Flower, but their work was far from being accomplished. Therefore, why had they gone? Were they following Flower? Had they already discovered that he had gone to London where he was likely to remain for the next few days?
