“All will be explained when we meet at Pisa. Away, now; to the Grand Duke—I will go to the negro and prepare him for your coming.”

“But allow me—”

“Not a word more, if you love me,” replied the violet-coloured domino, who, I was now convinced, was not Albert; it was not his voice—there was a mystery and a mistake; but I had become so implicated that I felt I could not retreat without sacrificing the parties, whoever they might be.

“Well,” said I, as I turned back to the palazzo, “I must go on now; for, as a gentleman and man of honour, I cannot refuse. I will give the packet to the Grand Duke, and I will also convey his treasure to Pisa, Confound this sky-blue domino!”

As I returned to the palazzo, I was accosted by the black domino.

“Milano!” replied I.

“Is all right, Felippo?” said he, in a whisper.

“All is right, Signor,” was my answer.

“Where is he?”

I pointed with my finger to a clump of orange-trees.
