“Wait a minute, Doctor,” Belknap said, as Davenport was about to leave. “I’m asking a few questions, and I want you to tell me as to those two shots that killed Mr Gleason. You don’t mind being present, Mrs Lindsay?”

“Indeed, no. I want to be. I want to know every bit of evidence, every clew to the murderer of my brother! I am not excited over the investigation, I only get nervous when I think you will not avenge the crime!”

“We’re trying our best,” returned Belknap. “What is your theory, Doctor Davenport?”

“I haven’t any,” and the doctor looked slightly embarrassed.

“Well,” Belknap thought to himself, “all these people act queer! Are they all shielding the same person? Is it the precious son of the house?”

“I don’t believe in laymen having theories,” Davenport went on. “Those are for the police to form and then to prove.” He spoke shortly, but in an even time, as one who was sure of what he wanted to say.

“All right,” agreed Belknap, “and to form and prove our theories, we must get all the evidence we can. Now, Doctor, as to those shots.”

The doctor became all the professional man again. “There’s no doubt as to the facts,” he replied, straightforwardly; “the fatal shot was most certainly fired first, and the shot in the shoulder some minutes later—after the man had been dead at least several minutes.”

“How do you, then, explain Mr Gleason’s ability to telephone a message that he was shot?”

“I don’t explain it—nor can I conceive of any explanation. It’s the strangest thing I ever heard of!”
