When we came to a stop the little man opened the door. We all alighted and followed him into a gloomy stone building. Through several passages we walked, and then our conductor led us into a small chamber, bare except for a half-dozen iron cots that stood in a row against the wall. A guard was at the doorway, but admitted us with a low bow after one glance at the man in black.

Leading us to the nearest cot, Mazanovitch threw back a sheet and then stood aside while we crowded around it. To my horror I saw the form of Madam Izabel lying dead before us. Her white dress was discolored at the breast with clots of dark blood.

“Stabbed to the heart,” said the guard, calmly. “It was thus they brought her from the train that arrived this afternoon from Matto Grosso. The assassin is unknown.”

Mazanovitch thrust me aside, leaned over the cot, and drew the woman’s left hand from beneath the sheet.

The little finger had been completely severed.

Very gently he replaced the hand, drew the sheet over the beautiful face, and turned away.

Filled with amazement at the Nemesis that had so soon overtaken this fierce and terrible woman, I was about to follow our guide when I found myself confronting a personage who stood barring my way with folded arms and a smile of grim satisfaction upon his delicate features.

It was Valcour—the man who had called himself de Guarde on board the Castina—the Emperor’s spy.

“Ah, my dear Senhor Harcliffe! Do we indeed meet again?” he cried, tauntingly. “And are you still keeping a faithful record in that sweet diary of yours? It is fine reading, that diary—perhaps you have it with you now?”

“Let me pass,” said I, impatiently.
