Jen started. Evidently David had returned before him in order to see Etwald, and to gain private speech with the doctor, had conducted him to Jaggard's sick-room. For the moment Jen--still suspicious of Sarby's behavior--had it in his mind to follow; but a few minutes of reflection convinced him that this was unnecessary. David did not know all the conversation which had taken place between himself and Isabella, therefore he could inform Etwald of nothing new. But, indeed, the major wondered why David wished to speak privately with the doctor. It looked, to his mind, as though the two men were in league. "I'll find out what it all means after I have had speech with Arkel," said Jen to himself. "The doctor cannot escape me, and if David has an understanding with him, I'll force them both to confess. There can be no harm in leaving them together for a few minutes." In this Jen was wrong, but, as he was only an amateur detective, he cannot be blamed very severely for his negligence at this particular moment. He acted--as he thought--for the best, and therefore hastened to explain to Arkel the position of affairs before the return of Dr. Etwald. Afterward, when the matter of the accusation and arrest were settled, he intended to have speech with David, and insist upon an explanation of the young man's mysterious behavior. Thus did the situation present itself to his inexperienced eyes. "Well, never mind Dr. Etwald just now," he said aloud, pointing to a chair. "He has his duties to perform, and I have mine. Sit down, Mr. Arkel. I suppose you wonder why I have sent for you?" "Well; no, major. I presume it is in connection with the case." "You are right. I wish to know if you have discovered anything new." "Yes. Your messenger, Battersea, was wandering about your grounds on that night." "Battersea!" cried Jen, thunderstruck. "Did he see the body carried off?" "He did not see it taken out of the house," explained Arkel, referring to some notes which he held in his hand, "but he saw it put into the carriage." "A carriage?" "Yes, which was waiting in the winding lane at the foot of your grounds. Two people carried the body between them--a man and a woman--but Battersea cannot give me their names." "I can, however," said Jen, grimly. "Oh, it is just as I thought." "What are the names, major?" asked Arkel, anxiously. "I'll give you the names later on, Mr. Inspector. In the meantime, be good enough to conclude your report of Battersea's confession. It interests me deeply." "I thought it would," replied Arkel, with a look of satisfaction. "Well, Battersea wondered at the body being put into the carriage--" "Did he know that it was Alymer's corpse?" interrupted Jen, sharply. "He guessed as much from the circumstance that the body was carried through your grounds to the lane where the carriage was waiting. You know, major, that this tramp is rather stupid, and it is not an easy thing for him to put two and two together."
