"I don't know a single soul in Italy," interrupted the other.
"But you will soon. People like you make acquaintances everywhere. But it's idle talk with strangers that I fear. Can I trust you as an Englishman not to talk of what you may see?"
"You may. I can't imagine what unlawful thing you are about to commit here. I am dying from curiosity. Can it be that you are really some sort of sorcerer? Go on! Trace your magic circle if that is your business, and call up the spirits of the dead."
A low grunt was the only answer to this speech uttered in a tone between jest and earnest. Cosmo watched from the breech of his gun with intense interest the movements of the man who objected so strongly to his presence but who now seemed to pay no attention to him at all. They were not the movements of a magician in so far that they certainly had nothing to do with the tracing of circles. The figure had stepped over to the seaward face of the tower and seemed to be pulling endless things out of the breast pocket of his jacket. The young Englishman got down from the breech of the gun, without ceasing to peer in a fascinated way, and moved closer step by step till he threw himself back with an exclamation of astonishment. "By heavens! The fellow is going to fish." . . . Cosmo remained mute with surprise for a good many seconds and then burst out loudly:
"Is this what you displayed all this secrecy for? This is the worst hoax I ever . . ."
"Come nearer, signore, but take care not to tangle all my twine with your feet. . . . Do you see this box?"
The heads of the two men had come together confidentially and the young traveller made out a cylindrical object which was in fact a round tin box. His companion thrust it into his hand with the request, "Hold it for me a moment, signore," and then Cosmo had the opportunity to ascertain that the lid of it was hermetically sealed. The man in the strange cap dived into the pocket of his breeches for flint and steel. The Englishman beheld with surprise his lately inimical companion squeeze himself between the massive tube of the piece of ordnance and the wall of stone and wriggle outwards into the depth of, the thick embrasure till nothing of him remained visible but his black stockings and the soles of his heavy shoes. After a time his voice came deadened along the thickness of the wall:
"Will you hand me the box now, signore?"
Cosmo, enlisted in these mysterious proceedings, the nature of which was becoming clear enough to him, obeyed at once, and approaching the embrasure thrust the box in at the full length of his arm till it came in contact with the ready hand of the man who was lying flat on his stomach with his head projecting beyond the wall of the tower. His groping hand found and snatched away the box. The twine was attached to the box and at once its length laid on the platform began to run out till the very end disappeared. Then the man lying prone within the thickness of the gun embrasure lay still as death and the young traveller strained his ears in the absolute silence to catch the slightest sound at the foot of the tower. But all he could hear was the faint sound of some distant clock striking somewhere in the town. He waited a little longer, then in the cautious tone of a willing accomplice murmured within the opening:
"Got a bite yet?"
