Carver went to the ’phone.
“He wants to speak to you.”
Carver had made a signal and now he took the receiver in his hand.
“I am sorry you have been disturbed, Mr. Lander,” he said, “but I’d like you to know officially that we warn you that an attempt has been made to get into this flat at—well ten minutes ago. What time would that be?”
“That would be about a quarter of two, I guess,” said Rex’s voice. “Thank you for telling me, Inspector, but I am not at all scared.”
Carver put the receiver on the hook and rubbed his hands.
“Do you think they will go there? What on earth is amusing you?” asked Tab irritably.
“I am intensely amused, I admit,” said Carver, “at the queer and simple error that our murderer made.”
