"And that Mr. Oliver should mysteriously disappear just after making such an announcement," said Audrey. "That certainly seems very surprising."

The two looked at each other, a question in the eyes of each, and Copplestone knew that the trouble in the girl's eyes arose from inability to understand what was already a suspicious circumstance.

"But after all, that may have been a mere coincidence," he hastened to say. "Let's hope things may be cleared. I only hope that Oliver hasn't met with an accident and is lying somewhere without help. I'm going to remain here for the night, however, and Stafford will come back early in the morning and go more thoroughly into things—I suppose there'll have to be a search of the neighbourhood."

They had walked slowly up a path on the side of the cliff as they talked, and now the girl stopped before a small cottage which stood at the end of the churchyard, set in a tree-shaded garden, and looking out on the bay. She laid her hand on the gate, glancing at Copplestone, and suddenly she spoke, a little impulsively.

"Will you come in and speak to my mother?" she said. "She was a great admirer of Mr. Oliver's acting—and she knew him at one time. She will be interested—and grieved."

Copplestone followed her up the garden and into the house, where she led the way into a small old-fashioned parlour in which a grey-haired woman, who had once been strikingly handsome, and whose face seemed to the visitor to bear traces of great trouble, sat writing at a bureau. She turned in surprise as her daughter led Copplestone in, but her manner became remarkably calm and collected as Audrey explained who he was and why he was there. And Copplestone, watching her narrowly, fancied that he saw interest flash into her eyes when she heard of Bassett Oliver's remark to the fisherman. But she made no comment, and when Audrey had finished the story, she turned to Copplestone as if she had already summed up the situation.

"We know this place so well—having lived here so long, you know," she said, "that we can make a fairly accurate guess at what Mr. Oliver might do. There seems no doubt that he went up the path to the Keep. According to Mr. Marston Greyle's statement, he certainly did not go to the house. Well, he might have done one of two other things. There is a path which leads from the Keep down to the beach, immediately opposite the big rocks which you have no doubt seen. There is another path which turns out of the woods and follows the cliffs towards Lenwick, a village along the coast, a mile away. But—at that time, on a Sunday afternoon, both paths would be frequented. Speaking from knowledge, I should say that Mr. Oliver cannot have left the woods—he must have been seen had he done so. It's impossible that he could have gone down to the shore or along the cliffs without being seen, too—impossible!"

There was a certain amount of insistence in the last few words which puzzled Copplestone—also they conveyed to him a queer suggestion which repulsed him; it was almost as if the speaker was appealing to him to use his own common-sense about a difficult question. And before he could make any reply Mrs. Greyle put a direct inquiry to him.

"What is going to be done?"

"I don't know, exactly," answered Copplestone. "I'm going to stay here for the night, anyway, on the chance of hearing something. Stafford is coming back in the morning—he spoke of detectives."
