"Why didn't you tell me?"
"It is not right that I should interfere with what burra sahib may choose to do. But after you have gone away tonight, some voice seems to tell me that Duncan sahib will be in danger. I have the name and address of this old man, sahib. I come here. I see the house dark. I enter. I find this place."
"But the elevator, Abdul. How did you operate that?"
