“Yes, señor, this way — please to follow me.” The little man led them down a long passage to a room at the back of the house.

A swarthy individual rose to greet them with a charming smile. The Duke introduced himself.

“But, yes, Excellency — my good friend Zavala wrote to me from London of your coming. Your case has safe arrival in the diplomatic bag — it is here beneath the table.” Rosas indicated a small, stout packing case. “You would like it opened? But certainly!” He rang the bell, and asked for a chisel and hammer; very soon the wooden case had been prized open, and an inner one of shining tin, about two feet long by a foot wide and eighteen inches deep, placed upon the table. “You would like the privacy to assure yourself of the right contents of the case, Excellency, is it not?” smiled Señor Rosas. “Please to make use of my room — no, no, it is no trouble — only ring when you have finished, that is all!” He slipped softly out of the room, closing the door behind him.

“Now let us look at our famous Hoyos.” De Richleau seized the ring that was embedded in the soft lead strip that ran round the top of the case, and pulled it sharply. A wire to which the ring was attached cut easily through the soft lead, and a moment later he had lifted out the two cedar cabinets of cigars.

Simon opened one with care, and ran his fingers lovingly down the fine, dark oily surface of the cigars. “Perfect,” he murmured; “travelled wonderfully!”

“But that is not all, my friend!” The Duke had opened the other box. The cigars were not packed in two bundles of fifty each, but in four flat layers of twenty-five to the row, and each layer was separated from the other by a thin sheet of cedar wood. Very carefully De Richleau lifted out the top layer on its cedar sheet, and then the next Simon looked over his shoulder and saw that, neatly packed in the place where the two bottom layers of cigars should have been, there reposed a full-sized, ugly-looking automatic.

The Duke removed it, together with two small boxes of ammunition and the packing. “You will find a similar trifle in the other box,” he remarked, as he gently lowered the two trays of cigars into the place where the pistol had lately been,

Simon unpacked the second box with equal care, the Duke taking the two layers of cigars from it, and placing them in the box before him. When all was done, there remained one box full of cigars, the other — empty.

“What — er — shall I do with this?” said Simon, a little doubtfully, as he gingerly picked up the other deadly-looking weapon, with its short blue steel barrel.

“Inside your left breast pocket, my son. It is far too large to carry upon your hip — the bulge would show!”
