By this time Alan and the inspector were walking along the road which led to Heathton. It was a bright, sunny morning, and Alan was in high spirits. How happy Blair's news would make Sophy!

"And Warrender, what about his death?" he asked. "Does Marlow know who killed him?"

"Strange as it may seem, he does not, Mr. Thorold. He is as ignorant as you or I. That death is a mystery still."

"But if Warrender was killed on the heath----"

"I can't explain, Mr. Thorold. Hear Marlow's story, and you will be as much in the dark as I am. But I suspect Lestrange."

"So did I," replied Alan, speaking in the past tense. "But I learned for certain that Lestrange was not in England on the night of the murder."

"I proved that, too," said Blair thoughtfully; "yet I can't help thinking there is some trickery. Lestrange is at the Good Samaritan?"

"Yes, dancing on Miss Marlow's doorstep in the hope of getting money."

"Does he receive any letters?"

"I don't know. Why?"
