“Well, from that to the conclusion that Jean Daval and Charpenais were accomplices required but a step. I took that step at the time of our conversation.”
“A little quickly, I think.”
“As a matter of fact, a material proof was wanted. Now I had discovered in Daval’s room, on one of the sheets of the blotting-pad on which he used to write, this address: ‘Monsieur A.L.N., Post-office 45, Paris.’ You will find it there still, traced the reverse way on the blotting-paper. The next day, it was discovered that the telegram sent by the sham flyman from Saint-Nicolas bore the same address: ‘A.L.N., Post-office 45.’ The material proof existed: Jean Daval was in correspondence with the gang which arranged the robbery of the pictures.”
M. Filleul raised no objection.
“Agreed. The complicity is established. And what conclusion do you draw?”
“This, first of all, that it was not the runaway who killed Jean Daval, because Jean Daval was his accomplice.”
“And after that?”
“Monsieur le Juge d’Instruction, I will ask you to remember the first sentence uttered by Monsieur le Comte when he recovered from fainting. The sentence forms part of Mlle. de Gesvres’ evidence and is in the official report: ‘I am not wounded.—Daval?—Is he alive?—The knife?’ And I will ask you to compare it with that part of his story, also in the report, in which Monsieur le Comte describes the assault: ‘The man leaped at me and felled me with a blow on the temple!’ How could M. de Gesvres, who had fainted, know, on waking, that Daval had been stabbed with a knife?”
Isidore Beautrelet did not wait for an answer to his question. It seemed as though he were in a hurry to give the answer himself and to avoid all comment. He continued straightway:
“Therefore it was Jean Daval who brought the three burglars to the drawing room. While he was there with the one whom they call their chief, a noise was heard in the boudoir. Daval opened the door. Recognizing M. de Gesvres, he rushed at him, armed with the knife. M. de Gesvres succeeded in snatching the knife from him, struck him with it and himself fell, on receiving a blow from the man whom the two girls were to see a few minutes after.”
