That evening, he wrote to the Procurer of the Republique at Rouen. He enclosed the threatening letter and solicited aid and protection.
The reply came at once to the effect that Arsène Lupin was in custody in the Prison de la Santé, under close surveillance, with no opportunity to write such a letter, which was, no doubt, the work of some imposter. But, as an act of precaution, the Procurer had submitted the letter to an expert in handwriting, who declared that, in spite of certain resemblances, the writing was not that of the prisoner.
But the words “in spite of certain resemblances” caught the attention of the baron; in them, he read the possibility of a doubt which appeared to him quite sufficient to warrant the intervention of the law. His fears increased. He read Lupin’s letter over and over again. “I shall be obliged to remove them myself.” And then there was the fixed date: the night of 27 September.
To confide in his servants was a proceeding repugnant to his nature; but now, for the first time in many years, he experienced the necessity of seeking counsel with some one. Abandoned by the legal official of his own district, and feeling unable to defend himself with his own resources, he was on the point of going to Paris to engage the services of a detective.
Two days passed; on the third day, he was filled with hope and joy as he read the following item in the ‘Réveil de Caudebec’, a newspaper published in a neighboring town:
“We have the pleasure of entertaining in our city, at the present time, the veteran detective Mon. Ganimard who acquired a world-wide reputation by his clever capture of Arsène Lupin. He has come here for rest and recreation, and, being an enthusiastic fisherman, he threatens to capture all the fish in our river.”
Ganimard! Ah, here is the assistance desired by Baron Cahorn! Who could baffle the schemes of Arsène Lupin better than Ganimard, the patient and astute detective? He was the man for the place.
The baron did not hesitate. The town of Caudebec was only six kilometers from the castle, a short distance to a man whose step was accelerated by the hope of safety.
After several fruitless attempts to ascertain the detective’s address, the baron visited the office of the ‘Réveil,’ situated on the quai. There he found the writer of the article who, approaching the window, exclaimed:
“Ganimard? Why, you are sure to see him somewhere on the quai with his fishing-pole. I met him there and chanced to read his name engraved on his rod. Ah, there he is now, under the trees.”
