“I was right,” said Raymond excitedly. “It is the Tunisian dagger.”

“Major Blunt hasn’t looked at it yet,” objected the inspector.

“Saw it the moment I came into the study,” said the quiet man.

“You recognized it, then?”

Blunt nodded.

“You said nothing about it,” said the inspector suspiciously.

“Wrong moment,” said Blunt. “Lot of harm done by blurting out things at the wrong time.”

He returned the inspector’s stare placidly enough.

The latter grunted at last and turned away. He brought the dagger over to Blunt.
