"You saw him? Spoke to him?"

"To be accurate, he spoke to me—down the coal-shaft, as I was examining it. I judged him to be simulating drunkenness. But his voice was a cultivated one—I should recognise it anywhere; and Mrs. Huggins, who saw and spoke with him, describes him as a long-faced man, of gentlemanly bearing, with a furred collar."

"Good Lord! Mortimer!" ejaculated Mr. Hucks, but inwardly.

"I need hardly point out to you that a bargee in a furred collar—"

"No, you needn't." Mr. Hucks rose from his chair. "See here, Glasson, you've come with a notion that I'm mixed up in this. Well, as it happens, you're wrong. I don't ask you to take my word—I don't care a d—n whether you believe me or not—only you're wrong. What's more, I'll give no promise to help—not to-night, anyway. But I'm goin' to look into this, and to-morrow I'll tell you if we play the hand together. To-morrow at nine-thirty, if that suits? If not, you can go and get the police to help."

"Time may be precious," hesitated Glasson.

"Mine is, anyway," Mr. Hucks retorted. "Let me see you out. No, it's no trouble. I'm goin' to look into this affair right away."

He handed the Doctor his lantern, opened the door for him, and walked with him three parts of the way across the yard. As they passed the caravan door his quick ear noted a strange sound within. It resembled the muffled yap of a dog. But Mr. and Mrs. Mortimer did not keep a dog.

He halted. "There's the gate. Good night," he said, and stood watching while Glasson passed out. Then, swinging on his heel, he strode back to the caravan.

"Mortimer!" he challenged, mounting to the third step and knocking.
