“They’re moving him,“ said Charlot.

“I’d better go, then.”

Henry went out.

“Can I do anything?” asked Roberta. She had spoken to nobody since Mike left her alone in the dining-room. Her voice sounded oddly in her ears.

“What?” Charlot saw her. “Oh, Robin, ask the maids to get plenty of boiling water. Doctors are so fond of boiling water, aren’t they? And Robin, I don’t know where the servants went, Tinkerton and Giggle, I mean. Could you find them and tell them there’s been an accident. And the lift. Somebody may want the lift. The doctor will. Did we shut the door?”

“I’ll see.”

“Thank you so much.”

Roberta hurried away and found time confusedly to marvel at Charlot’s command of her nerves and of the situation. The Lampreys, she thought hurriedly, do rise to situations. She delivered the message to the maids. Now she must return to the landing. The lift was still open. Roberta stood stock-still with her hands on the doors, drilling her thoughts, telling them that he was gone, that she must look inside the lift. And, with a great effort, she lifted her head and looked. A little above the place where Lord Wutherwood had sat was a bright steel boss in the lift wall. In the centre of the boss was a small hollow which seemed to be stained. As she stared at it the stain grew longer. She heard a tap, a tiny dab of sound. She looked at the leather top of the seat. In the dent made by Lord Wutherwood she saw a little black pool where his blood had dropped from the stain on the wall. Back to the pantry, running as fast as she could go… A yellow duster…Then the lift again…It had looked so small a pool but it spread into her cloth and smeared over the leather… Now the wall. She heard a bell ringing. That would be someone who wanted the lift. Back on the landing, she slammed the doors and the lift at once sank beneath her fingers. Henry came out from 26 and looked at the cloth in her hands. He seemed like a figure in a dream and spoke like one.

“Clever Robin,” said Henry. “But it won’t do much good, you know. You can’t wipe away murder.”

Roberta had pushed that word out of her thoughts. She said: “It’s not that — I mean I wasn’t trying to do that. Only people will be using the lift. It looked so frightful.”
