To learn the truth, he thought it advisable to call at "The Wigwam" and interrogate Dido. With the evidence of Jaggard to go on, the major felt satisfied that he could by threatening her with arrest, force her into confessing the whole nefarious plot. Who had thieved the devil-stick? Who had slain Maurice? Who had stolen the body? Undoubtedly, Etwald was the villain who was guilty of all three crimes, and the evidence of Dido would be sufficient to convict him of the deeds. "Yes," said Jen to himself that night, as he retired to bed, "to-day I have learned sufficient to implicate Etwald; to-morrow I shall be able to convict him. Dido must confess or go to prison." Angered by the selfish way in which David had acted, Jen did not communicate his discoveries to the young man. During the night he took counsel with himself, and the next morning he acted upon the plans which he had formed. These were, to see Dido and force the truth from her, to send Battersea to Deanminster to fetch both Arkel and Dr. Etwald to "Ashantee," and finally to communicate his discoveries to the inspector and get him to arrest Etwald. Once in prison, and the doctor, intimidated by a fear of death at the hands of justice, might confess his crimes, and his reasons for committing them. This straightforward course was the only one to pursue. After breakfast, therefore, the major wrote two notes. One for Arkel, asking him to be at "Ashantee" by noon, as the writer had important matters to discuss; the other for Etwald, requesting him to call and see Jaggard, who, added Jen, significantly in the letter, had recovered his senses. Having thus prepared his trap for the doctor to walk into, Jen delivered the letters to Battersea, with instructions to set off at once for Deanminster. The tramp, anxious to keep in favor with Jen for cupboard reasons, lost no time in departing, and when the major had seen him safely out of the gates, he took his way toward "The Wigwam" for the all-important interview with Dido. Before his departure he had left a message for David, who had not made his appearance at breakfast, requesting the young man to be in the library at noon. "If I can force the truth out of Dido," thought Jen, strolling slowly along in the hot sunshine, "I may get the better of Etwald. Then, when David sees that the doctor is in the trap, and in danger of arrest for murder, he may relate what he knows. Though upon my word," considered the major, frowning, "I don't see what information he can possibly add to what I have obtained from Jaggard, or what I am likely to wring from the unwilling lips of Dido. Etwald is the guilty person. David can tell me no more than that."
