"A man would want some nerve to come down from that height," the latter remarked.

"Any man, or woman either for that matter," Henshaw returned dogmatically, "would not hesitate to take the risk as an alternative to being trapped up there with his victim."

"You are not suggesting it might have been a woman who was seen sliding down the rope?" Gifford asked pointedly.

Henshaw shrugged. "I suggest nothing as to the person's identity," he replied in a sharply guarded tone. "That is now what remains to be discovered."

CHAPTER XVIII

THE LOST BROOCH

The police authorities with Henshaw and Morriston went off with the rope to experiment in the room of the tragedy.

"I don't suppose we are wanted," Kelson said quietly to Gifford; "let's go for a turn round the garden. I wonder where Muriel has got to."

They found Miss Tredworth on the lawn. "I am waiting for Edith," she said.

"We'll stroll on and Gifford can bring Miss Morriston after us," Kelson suggested, and the lovers moved away, leaving Gifford, much to his satisfaction, waiting for Edith Morriston.
