“I say, though,” expostulated Horace, “my sister’s awfully upset, you know. Is it absolutely necessary?”

“Aye, sir, it is!” said the Inspector. “But there’s no need for me to see her in here. Perhaps in some other room ...”

“The drawing-room is next to this,” the butler put in; “they’d be nice and quiet in there, Sir Horace.”

“Sir!”

A stout sergeant appeared at the library door.

“As soon as the body has been removed, you will lock the room and bring the key to me. And you will return here and see that no one attempts to get into the room. Understand?”

“Yessir!”
