"Mr. Narkom," he said, "this case stumps me. I believe there's magic in it, if you ask me; and as the only way to fight magic is with magic, I'm going to consult a clairvoyante, and if one of those parties can't give me a clue, I don't believe the mystery ever will be solved. I know of a ripping good one, but she is over in Ireland, and as it's a dickens of a way to go, I shan't be able to get back before the day after to-morrow at the earliest. But—look here, sir, I'll tell you what! This is Tuesday evening, isn't it? Now if you and Mr. Van Nant will be at Captain Morrison's house on Thursday evening at seven o'clock, and will wait there until I come, I'll tell you what that clairvoyante says, and whether there's any chance of this thing being solved or not. Is that agreeable, Mr. Van Nant?"

"Quite, Mr. Headland. I'll be there promptly."

"And stop until you hear from me?"

"And stop until I hear from you."

"Right you are, sir. Now then, Mr. Narkom, if you'll let the chauffeur whisk me over to the station, I'll get back to London and on to the earliest possible train for Liverpool, so as to be on hand for the first Irish packet to-morrow. And while you're looking for your hat, sir—good evening, Mr. Van Nant—I'll step outside and tell Lennard to crank up."

With that, he passed out of the studio, walked down

the hall, and went out of the house. And half a minute later, when the superintendent joined him, he found him sitting in the limousine and staring fixedly at his toes.

"My dear Cleek, did you find anything?" he queried as he took a seat beside him, and the motor swung out into the road and whizzed away. "Of course, I know you've no more idea of going to Liverpool than you have of taking a pot-shot at the moon; but there's something on your mind. I know the signs, Cleek. What is it?"

The response to this was rather startling.

"Mr. Narkom," said Cleek, answering one question with another, "what's the best thing to make powdered bismuth stick: lard, cold cream, or cocoa butter?"
