Quarles nodded.

"Of course, there is the possibility that Dr. Smith is not dead," I went on, "that he has disappeared intentionally, hoping to defraud the insurance company. Were you thinking of that, Zena?"

"No; I was only wondering why the body had not been found."

"And you, professor?"

"Oh, I haven't developed a theory yet! If no body is found, I presume the company will withhold the payment of the money for a time."

"Naturally, I didn't discuss that question with them," I returned. "I imagine no very thorough search of the doctor's papers has yet been made, for Mrs. Smith knew nothing definite about the insurance, and, indeed, very little about her husband's affairs."

"Well, we must wait for the body," said the professor.

"You have the same opinion as I have, and expect it to come ash.o.r.e."

"I have formed no opinion," he answered, "but, judging from your account, I should think the body will be found presently. When it is I should like to see it, Wigan. The case doesn't really interest me yet, but my presentiment does. When I feel my particular corner of the web of existence trembling I--but it is too late to get on my hobby to-night. I'm tired, and I dare say you and Zena want to have a talk.

You're a lucky dog, Wigan, a very lucky dog."

He chuckled as he left the room, and Zena and I looked at each other in astonishment. It was the first intimation he had given that he knew our secret. He declared later that he had known it exactly as long as we had, which was probably an exaggeration; but at any rate it made things easier for us.

I returned to Riversmouth next day, and two days later the doctor's body was found. As I had suggested to Zena, it had evidently been caught by another current, and was discovered among the rocks in a little bay about half a mile east of the coves. A lad saw it from the top of the cliffs and gave information.

I telegraphed to Quarles at once, and he arrived in Riversmouth that afternoon.

Mrs. Smith, Patrick Evans, and the solicitor, Ferguson, had already identified the body when Quarles and I went to see it at the mortuary.

The professor spent a long time examining the dead man and his clothing. He was particularly interested in the collar of his coat, and in certain rents in the coat and trousers. I must confess he seemed to be looking for a mystery where none existed. A silver watch found in the dead man's pocket had the initials "R. S." on it, and a signet ring on his finger also bore these initials. There could be no doubt of the man's ident.i.ty.

"What are you looking for?" I asked.

"Nothing----"

"That presentiment is misleading you."

"Maybe," said Quarles.

"There is no doubt that he was drowned, and there is not the slightest indication that he was the victim of foul play before he was in the water."

"I am inclined to agree with you."

"The only question is whether his death was the result of an accident or whether he committed suicide."

"I shouldn't like to express an opinion," Quarles returned shortly.

"By the way, Wigan, who found the body?"

"A boy belonging to the town."

"I suppose we can get hold of him?"

"He is ready to talk to anyone about it."

"We'll go and find him," said Quarles. "I'm staying in Riversmouth to-night; no, not with you. I don't want to be identified with the case in any way. When is the inquest?"

"The day after to-morrow."

"Then to-morrow afternoon you might show me these coves."

"Certainly."

"Now for this boy."

The wind was blowing half a gale as we went through the town.

"It has been blowing like this ever since the night the doctor disappeared, hasn't it?" asked Quarles.

"Worse than this part of the time. What's the theory, professor?"

"I'm wondering whether there is not some way of clearing up the accident or suicide question."

We found the lad at his home, and Quarles listened attentively to his graphic description of seeing the water playing with the corpse as it lay caught on the rocks.

"Had you gone that way on purpose to see if it had come ash.o.r.e?" asked Quarles.

"I had and I hadn't. You don't know old Clay, I suppose. He's a fisherman who thinks he knows everything, and he said it was impossible for a body to be washed up on that side of the east cliff."

"And you knew better?"

"It wasn't that. There were several people standing round at the time, and they laughed at old Clay for being so positive. He was wrong, you see."

"Evidently. Do you remember who was there at the time?"

"I didn't notice. I was listening to what Clay was saying. I don't suppose he'll talk so much after this."

Quarles made no comment on what the lad had said as we walked to the end of the street together, and we parted after arranging our visit to the coves on the following afternoon.

Next day about noon I walked up to see Mrs. Smith. The a.s.sistant, Evans, came to me, bringing me her apologies. Unless it were anything of the gravest importance, would I mind coming again?

"The fact is, she has been upset this morning," Evans went on. "A gentleman unexpectedly turned up to see the doctor about a new patient coming here. He had not heard of the doctor's tragic death, and Mrs.

Smith had to explain."

"Very trying for her," I said.

"And, to make it worse, the man was rather stupid," said Evans. "He didn't seem to understand the position, nor why the doctor's death should prevent arrangements being made. He appeared to have got it into his head that we were unwilling to let him see how the house was conducted. I was called in to the rescue, and I took him over the house. If the weak-minded patient is a relative, I should think the disease is hereditary."

"Why?"

"He could not understand any explanation," said Evans. "He even selected a bedroom which happened to be mine, and would go into details why it was exactly the room he desired. Of course, the house is to be given up. I believe the relations of the three patients we have already have been written to."

"I wanted to ask Mrs. Smith if the doctor's papers throw any light upon his death."
