“Certainly,” said Sinclair “I should like you to do so, it will show what you are made of.”
“You say there was no one in the room. Is that absolutely certain?”
“The constable, as I told you, is rather a stupid person, but he never left the room after they burst open the door, and it was only a few minutes after that Giles returned with Sefton.”
“What about means of exit?” said Fletcher scanning his notes.
“A thorough search was made, first by the constable and the others, and afterwards by Sergeant Andrews from Ashstead. The windows were securely fastened, and there was no other door, and no trap doors or secret panels that can be found.”
“The door was locked, where was the key?” asked Fletcher again.
His Chief gave a chuckle. “Good!” he said, “there was no key found.”
“One last question, sir. What was the weapon?”
“An old dagger, with a thin blade. The waistcoat had been torn back, and the blade driven in between the ribs from the back, and had penetrated the heart. It had been cleverly done and seemed to show a knowledge of anatomy, but we must not jump to conclusions.”
“This is a tough nut, sir.”
