This quite inconceivable death ride spread such consternation among the Moors that their attack was half-hearted and the battle was won without resistance.

This, together with numberless other feats of bravado, went to make up the heroic legend of Perenna.  It threw into relief the superhuman energy, the marvellous recklessness, the bewildering fancy, the spirit of adventure, the physical dexterity, and the coolness of a singularly mysterious individual whom it was impossible not to take for Arsene Lupin, but a new and greater Arsene Lupin, dignified, idealized, and ennobled by his exploits.

One morning, a fortnight after the double murder in the Boulevard Suchet, this extraordinary man, who aroused such eager interest and who was spoken of on every side as a fabulous and more or less impossible being:  one morning, Don Luis Perenna dressed himself and went the rounds of his house.

It was a comfortable and roomy eighteenth-century mansion, situated at the entrance to the Faubourg Saint-Germain, on the little Place du Palais-Bourbon.  He had bought it, furnished, from a rich Hungarian, Count Malonyi, keeping for his own use the horses, carriages, motor cars, and taking over the eight servants and even the count’s secretary, Mlle. Levasseur, who undertook to manage the household and to receive and get rid of the visitors—­journalists, bores and curiosity-dealers—­attracted by the luxury of the house and the reputation of its new owner.

After finishing his inspection of the stables and garage, he walked across the courtyard and went up to his study, pushed open one of the windows and raised his head.  Above him was a slanting mirror; and this mirror reflected, beyond the courtyard and its surrounding wall, one whole side of the Place du Palais-Bourbon.

“Bother!” he said.  “Those confounded detectives are still there.  And this has been going on for a fortnight.  I’m getting tired of this spying.”

He sat down, in a bad temper, to look through his letters, tearing up, after he had read them, those which concerned him personally and making notes on the others, such as applications for assistance and requests for interviews.  When he had finished, he rang the bell.

“Ask Mlle. Levasseur to bring me the newspapers.”

She had been the Hungarian count’s reader as well as his secretary; and Perenna had trained her to pick out in the newspapers anything that referred to him, and to give him each morning an exact account of the proceedings that were being taken against Mme. Fauville.

Always dressed in black, with a very elegant and graceful figure, she had attracted him from the first.  She had an air of great dignity and a grave and thoughtful face which made it impossible to penetrate the secret of her soul, and which would have seemed austere had it not been framed in a cloud of fair curls, resisting all attempts at discipline and setting a halo of light and gayety around her.
