“Allow me, sir,” said Parker, and sprang forward to assist him. He deposited the articles neatly on a chair by the door. Poirot watched him with approval.

Parker seated himself with an apologetic bend of the head.

“Now what do you think I asked you to come here for this morning—eh?”

Parker coughed.

“I understood, sir, that you wished to ask me a few questions about my late master—private like.”

Précisément,” said Poirot, beaming. “Have you made many experiments in blackmail?”

“Sir!”

The butler sprang to his feet.
