“They did not know!” he answered. “When next I visited my own house, it was at night, and by a way not known, save to myself.” As he spoke, the canine teeth began to show. He knew that what he had to tell was wrong; and being determined to brazen it out, the cruelty which lay behind his strength became manifest at once. Somehow at that moment the racial instinct manifested itself. Spain was once the possession of the Moors, and the noblest of the old families had some black blood in them. In Spain, such is not, as in the West, a taint. The old diabolism whence sprung fantee and hoo-doo seemed to gleam out in the grim smile of incarnate, rebellious purpose. It was my cue to throw my antagonist off his guard; to attack the composite character in such way that one part would betray the other.

“Strange!” I said, as though to myself again. “To come in secret into a house occupied by another is amongst civilised people regarded as an offence!”

“The house is my own!” he retorted quickly, with a swarthy flush.

“Strange, again!” I said. “When Mrs. Jack rented the castle, there was no clause in her agreement of a right to the owner to enter by a secret way! On the contrary such rights as the owner reserved were exactly specified.”

“A man has a right to enter his own house, when and how he will; and to protect the property which is being filched from him by strangers!” He said the last words with such manifest intention of offence that I stood on guard. Evidently he wanted to anger me, as I had angered him. I determined that thenceforward I should not let anything which he might say ruffle me. I replied with deliberate exasperation:

“The law provides remedies for any wrongs done. It does not, that I know of, allow a man to enter secretly into a house that he has let to another. There is an implied contract of peaceful possession, unless entry be specified in the agreement.” He answered disdainfully:

“My agent had no right to let, without protecting such a right.”

“Ah, but he did; and in law we are bound by the acts of our agents. ‘Facit per alium’ is a maxim of law. And as to filching, let me tell you that all your property at Crom is intact. The pieces of paper that you claimed were left in the book; and the book has remained as you yourself placed it on the shelf. I have Mrs. Jack’s word that it would be so.” He was silent; so, as it was necessary that the facts as they existed should be spoken of between us, I went on:

“Am I to take it that you read the private papers on the table of the library during your nocturnal visit? By the way, I suppose it was nocturnal.”

“It was.”
