"What is it?" queried the travellers anxiously.

"The man is dead!"

Never had the Paris diligence been so late in starting from Mézidon; and when finally, with much cracking of whip and rattling of chains, it thundered along the cobblestones of the Grande Rue, it was without its full complement of passengers.

M. le Commissaire de Police had ordered the detention of most of them as witnesses of the occurrences which culminated in the death of Hippolyte Darnier, who was known to the commissaire as an employé on the police staff at Caen.

It was no use grumbling. No one who had seen or spoken to the woman in the black cloak could be allowed to leave the city until M. le Procureur Imperial in Caen had granted them leave to do so.

In the meanwhile M. le Sous-Préfet, who was quite hopelessly out of his depth, interrogated the witnesses without eliciting more than a noisy and confused account of the events of the past few hours wherein the weather, the bad state of the roads, and the good wines of the "Cheval Blanc" vied in importance with the doings of a so-called mysterious nun, of whom nothing had been seen by anybody save the point of a chin and a voluminous black cloak and hood. By the time that the sous-préfet had jotted down these miscellaneous depositions, it was discovered that the mysterious personage in question had disappeared. Whereupon search parties were sent abroad in every direction, with strict orders to bring any woman who was seen wearing any kind of a black cloak forthwith before M. le Commissaire, whilst the sous-préfet, freely perspiring under the effort, wrote out a detailed and wholly unintelligible report of the incidents, which he dispatched by mounted courier to his chief at Caen.

The search parties, after two or three hours' diligent scouring of the neighbourhood, brought back an inoffensive farm servant, who was trudging home from her milking, wrapped in a black shawl; the kitchen wench from the Hôtel de Madrid, who had gone out to meet her sweetheart and had borrowed her mistress's black cloak for the occasion; and old Madame Durand, the caretaker at the church of St. Pierre, who always wore a black gown as an outward symbol of her official position and responsible calling.

One lad, more intelligent than the rest, while wandering along the tow-path of the river, had espied a black cloak and hood floating down-stream until its progress was arrested by a clump of rushes. The lad fished for the cloak with a barge-pole and succeeded in landing it. He brought it in triumph to Mézidon, where he became the hero of the hour.

Late in the evening M. Laurens, préfet of Caen, received his subordinate's report. At once he communicated with M. Carteret, the chief commissary of police. The two, fearing that the officious secret agent would keep them out of their beds for the next two hours, with God knows what orders to proceed to Mézidon in the middle of the night, decided to say nothing to him until the morning. After all, the matter was not of such paramount importance. Darnier, they argued, had had too much to drink and had a fit of apoplexy in an overheated room.
