“All the inquiries I have made point to the one fact I have already suggested,” the detective said. “At Scotland Yard we received a request from your Excellency that we should carefully investigate the matter, and we are doing so to the very best of our ability.”

“I’m sure you are. I well recollect now signing a formal request to your Department to make searching investigation.”

At that moment a clerk entered, bearing a file of papers, which he placed before His Excellency.

“Now,” exclaimed the latter, “let us see what reply we received from the police of Livorno;” and he slowly turned over letter after letter. The correspondence had evidently been considerable. Its magnitude surprised the detective.

Suddenly the Count paused, and his brows contracted as he read one of the official letters. He glanced at the signature, and saw it was that of the Marquis Montelupo, Minister of Foreign Affairs at Rome. Twice he read it through. It was a long despatch, closely written, and as the Ambassador re-read it his brow darkened.

Again he touched the electric bell, and a second time summoned the Secretary of Embassy.

When the latter appeared His Excellency beckoned him into an inner room, and, taking the file of papers with him, left the Inspector alone with The Times.

After the lapse of some ten minutes both men returned.

“But what I desire to know, and that clearly, is, why this despatch was never handed to me,” His Excellency was saying angrily as they emerged.

“You were away at Scarborough, therefore I attended to it myself,” the Secretary answered.
