On the great night the stream of equipages which set down the guests at Les Acacias extended for close on a kilomètre from the park gates to the confines of the city, and those who were not watching the fireworks at the Old Château stood about on the road, in spite of the cold, to see the gorgeous liveries, the painted coaches and caparisoned horses which were a regular feast for the eyes. For hours the streets were thronged. Only the narrow little Rue aux Juifs on the outskirts of the city appeared dark, solitary and unfestive. It consisted for the most part of tumble-down, half-derelict houses, the owners of which had been out of France for many years. And to-night, when the rest of Caen was out to make merry, only one of the low, grim-faced houses showed any sign of life. Here a feeble light shone dimly through the cracks of an ill-fitting shutter on one of the floors above, and anyone who had taken the trouble to be on the watch would have seen dark forms, wrapped to the chin, gliding furtively in and out of the door.

But the military, the police and the municipal servants were alike engaged in keeping watch over Les Acacias, the stately residence which sheltered the most precious life in Europe.

The rout was kept up till the small hours of the morning. It was two o'clock before the last equipage drove through the monumental gates of Les Acacias, and these were finally closed upon the departing guests. But for an hour after that the roads around the house were still thronged with people too excited to go to bed. They swarmed around the encircling wall, above which they could only see the glimmer of lights behind the shuttered windows, and tried to peer through the wrought-iron gates, happy to see how completely their Emperor trusted them, and that he disdained the usual paraphernalia of military guards and sentinels—the relics of bygone times. The house was lighted up; no doubt a number of lackeys would be astir keeping watch over the illustrious guest, but there was no glimmer of fixed bayonets within the gates, no tramp of martial feet up and down the circular drive.

Only at three o'clock did the citizens of Caen finally decide to go to bed. By half-past three the approaches to Les Acacias, as well as the streets, were at last deserted; the houses in the city had closed down their lights; only in the distance the house in which the Emperor slept was illuminated from within; but it, too, now appeared absolutely still.

Then suddenly the slumbering city was awakened by an awful sound—a terrific crash which broke the window panes of hundreds of houses, and which reverberated for many kilomètres around. Fragments of wood and stone and tiles appeared to rain down from the skies like death-dealing projectiles, crashing through the roofs of some houses on the confines of the city and causing much damage, fortunately without any loss of life.

There was hardly a citizen inside the town who did not immediately jump out of bed, with beating heart and blanched cheeks and lips that quivered with horror, as he murmured the ominous words:

"Les Acacias! The Emperor! My God!"

Within a few minutes the garrison was astir. The whole sky was now suffused with a weird and lurid glow. In the direction of St. Martin, where stood Les Acacias, vivid tongues of flame were seen to leap intermittently into the night. The streets leading thither soon became crowded with people, clad in promiscuous garments, all running in the one direction, and headed by a company of infantry and a squadron of cavalry, rushing along with buckets, pumps and ladders, in the wake of the hastily summoned official fire-brigade. The confusion threatened to grow serious. The city police were quite unable to cope with it, and the military alone were in a measure able to enforce some semblance of order.

Only the Rue aux Juifs, with its crazy houses, remained as before, silent and comparatively deserted. The distant conflagration lit up with a weird glow the ramshackle façades which lined the narrow thoroughfare. Neither the police, nor the military, nor yet the few sight-seers who drifted down the street in search of a short cut to the scene of excitement, had a mind to notice the sombrely clad passers-by who halted outside the door of one of these grim-faced abodes, about half-way down the street.

Two men, dressed in rough blouses, and with wide-brimmed hats pulled over their eyes, appeared to be on guard at the door, and as each person passed from the street into the house, one of these men uttered a whispered challenge: "The fearful wild fowl is abroad." And instantly was heard the equally whispered reply: "And the wild duck comes with a feather in her mouth."
