My only policy was to wait and to watch.

I recollected Ella’s appeal to me to remain silent concerning the scoundrel under whose banal thrall she had so mysteriously fallen, and I feared that if I made my statement it might lead to the fellow’s arrest.

What, I wondered, was the true explication of the mystery of the unknown girl being found in that room wherein the three thieves were entrapped? Who was she? What did Lucie know concerning her?

A great fear possessed me that the police, in searching, would discover Lucie in Leghorn, though in Italy the detectives always find more difficulty in tracing foreigners than the Italians themselves. Every Italian, when he moves his habitation even from one street to the other, is compelled to give notice to the police. But not so the large foreign floating population who are for ever moving over the face of what is essentially a tourists’ country.

Another great crash upon the door awakened me to a sense of my peril, should these men succeed in escaping. With as little compunction as they had struck down the guard, they would, I knew, strike me down, and even though I had a revolver they were three to one. Besides, a pistol is no use against a knife in the hands of such an expert as the young thief in the grey hat whom they had so swiftly taken into their confidence.

With regret that they had seized that large amount in money, and yet in the hope that they might regain their liberty and remain for some time longer—at least until I had learned the truth concerning my well-beloved—I crept softly back along the great salon, feeling my way before me with my hands. So thick was the carpet that my feet fell noiselessly, and my escape was rendered all the more easy by the noise the men were making by trying to batter down the door.

Swiftly I retraced my steps along the corridors, through the picture-gallery and the older wing of the great house, until I came to the long dim stone corridor. I shuddered as I passed into it, for there lay still undiscovered, and in the same position in which the assassins had left it, the body of the unfortunate police agent who had been left in charge of the fugitive’s property which had been seized by the Government. On tiptoe I approached it, and bending, replaced the revolver.

Then with a final glance at the evidence of a horrible deed—a deed committed for the lust of gold—I crept out into the early morning air which blew fresh and cool from over the mountains, causing the leaves of the vines to rustle while a loose sun-shutter creaked mournfully as it swung to and fro overhead.

Retracing my steps through the vineyard I gained the high-road, when the fancy took me to ascend to the back of the villa and listen if I could hear the imprisoned intruders.

Hardly had I reached the top of the hill when the truth was revealed to me, as I expected. Their voices could be distinctly heard, for one of those strongly barred windows that looked out upon the roadway was that of the room wherein the absconding ex-Minister had concealed the money he had filched from the public purse.
