Carrados turned to the lieutenant.
“A rather delicate job for you now, Mr Hollyer. I want you to go up to your sister, wake her, and get her into another room with as little fuss as possible. Tell her as much as you think fit and let her understand that her very life depends on absolute stillness when she is alone. Don’t be unduly hurried, but not a glimmer of a light, please.”
Ten minutes passed by the measure of the battered old alarum on the dresser shelf before the young man returned.
“I’ve had rather a time of it,” he reported, with a nervous laugh, “but I think it will be all right now. She is in the spare room.”
“Then we will take our places. You and Parkinson come with me to the bedroom. Inspector, you have your own arrangements. Mr Carlyle will be with you.”
They dispersed silently about the house. Hollyer glanced apprehensively at the door of the spare room as they passed it but within was as quiet as the grave. Their room lay at the other end of the passage.
“You may as well take your place in the bed now, Hollyer,” directed Carrados when they were inside and the door closed. “Keep well down among the clothes. Creake has to get up on the balcony, you know, and he will probably peep through the window, but he dare come no farther. Then when he begins to throw up stones slip on this dressing-gown of your sister’s. I’ll tell you what to do after.”
The next sixty minutes drew out into the longest hour that the lieutenant had ever known. Occasionally he heard a whisper pass between the two men who stood behind the window curtains, but he could see nothing. Then Carrados threw a guarded remark in his direction.
“He is in the garden now.”
Something scraped slightly against the outer wall. But the night was full of wilder sounds, and in the house the furniture and the boards creaked and sprung between the yawling of the wind among the chimneys, the rattle of the thunder and the pelting of the rain. It was a time to quicken the steadiest pulse, and when the crucial moment came, when a pebble suddenly rang against the pane with a sound that the tense waiting magnified into a shivering crash, Hollyer leapt from the bed on the instant.
