Mon Souci, the seat of that eccentric and eremitical genius the Comte de Rueil, is situated three kilometres from Verneuil. It is a sorrowful and decayed château, desolate at the termination of its neglected avenue of pines. The mournful state of a nobility without an allegiance surrounds it. The stone nymphs droop greenly over their dry and mouldering fountains. An occasional peasant creaks with a single wagon-load of wood along the ill-forested glades. It has the atmosphere of sunset at all hours of the day. The woodwork is dry and gaping for lack of paint. Through the jalousies one sees the prim salon, with its beautiful and faded furniture. Even the last of its ill-dressed, ill-favoured women has withered away from Mon Souci, with her inbred, exaggerated features and her long white gloves. But at the rear of the château a chimney smokes incessantly. It is the furnace of the laboratory, the only living and modern thing among the old and dying; the only place tended and loved, petted and spoiled, heir to the long solicitude which counts of a more light-hearted day had given to stable and kennel, portrait-gallery and ballroom. And below, in the cool cellar, lie row upon row the dusty bottles, each an enchanted glass coffin in which the Sleeping Beauty of the vine grows ever more ravishing in sleep.

As the Peugeot came to a standstill in the courtyard, the driver observed with considerable surprise that he was not the count's only visitor. An immense super-Renault, like a merveilleuse of the Directoire, all bonnet and no body, had been drawn so ostentatiously across the entrance as to embarrass the approach of any new-comer. Its glittering panels were embellished with a coat of arms, and the count's elderly servant was at that moment staggering beneath the weight of two large and elaborate suit-cases, bearing in silver letters that could be read a mile away the legend: "Lord Peter Wimsey."

The Peugeot driver gazed with astonishment at this display, and grinned sardonically. "Lord Peter seems rather ubiquitous in this country," he observed to himself. Then, taking pen and paper from his bag, he busied himself with a little letter-writing. By the time that the suit-cases had been carried in, and the Renault had purred its smooth way to the outbuildings, the document was complete and enclosed in an envelope addressed to the Comte de Rueil. "The hoist with his own petard touch," said the young man, and, stepping up to the door, presented the envelope to the manservant.

"I am the bearer of a letter of introduction to monsieur le comte," he said. "Will you have the obligingness to present it to him? My name is Bredon—Death Bredon."

The man bowed, and begged him to enter.

"If monsieur will have the goodness to seat himself in the hall for a few moments. Monsieur le comte is engaged with another gentleman, but I will lose no time in making monsieur's arrival known."

The young man sat down and waited. The windows of the hall looked out upon the entrance, and it was not long before the château's sleep was disturbed by the hooting of yet another motor-horn. A station taxi-cab came noisily up the avenue. The man from the first-class carriage and the luggage labelled P. D. B. W. were deposited upon the doorstep. Lord Peter Wimsey dismissed the driver and rang the bell.

"Now," said Mr. Bredon, "the fun is going to begin." He effaced himself as far as possible in the shadow of a tall armoire normande.

"Good evening," said the new-comer to the manservant, in admirable French, "I am Lord Peter Wimsey. I arrive upon the invitation of Monsieur le comte de Rueil. Monsieur le comte is at liberty?"
