"You are late," said the incognito, when we had walked so far away from the palazzo as to be out of hearing of the crowd. "I did not make up my mind to come until an hour ago," replied I. "I was so afraid that you would not come. Albert was sure that you would, he was right. He told me just now that he had spoken to you." "What! was that Albert in the rose-coloured domino?" "Yes; but I dare not stay now--my father will be looking for me. Albert is keeping him in conversation. In half an hour he will speak to you again. Has he explained to you what has occurred?" "Not one word." "If he has not had time--and I doubt if he will have, as he must attend to the preparations--I will write a few lines, if I can, and explain, or at least tell you what to do; but I am so harassed, so frightened! We do indeed require your assistance. Adieu!" So saying, the fair unknown tripped hastily away. "What the deuce is all this?" muttered I, as I watched her retreating figure. "Albert said that he had an appointment, but he did not make me his confidant. It appears that something which has occurred this night occasions him to require my assistance. Well, I will not fail him." For about half an hour I sauntered up and down between the lines of orange-trees which were dressed up with variegated lamps, and shed their powerful fragrance in the air: I ruminated upon what might be my friend's intentions, and what might be the result of an intrigue carried on in a country where the stiletto follows Love so close through all the mazes of his labyrinth, when I was again accosted by the violet-coloured domino. "Hist!" whispered he, looking carefully round as he thrust a paper into my hand; "read this after I leave you. In one hour from this be you on this spot. Are you armed?" "No," replied I; "but Albert--" "You may not need it; but nevertheless take this,--I cannot wait." So saying, he put a stiletto into my hand, and again made a hasty retreat. It had been my intention to have asked Albert what was his plan, and further why he did not speak English instead of Italian, as he would have been less liable to be understood if overheard by eavesdroppers; but a little reflection told me that he was right in speaking Italian, as the English language overheard would have betrayed him, or at least have identified him as a foreigner. "A very mysterious affair this!" thought I; "but, however, this paper will, I presume, explain the business. That there is a danger in it is evident, or he would not have given me this weapon;" and I turned the stiletto once or twice to the light of the lamp next to me, examining its blade, when, looking up, I perceived a black domino standing before me.
