Arthur had had time to invent a story to account for his unexpected appearance on this occasion.

'From what you tell me,' said he, 'I am sure that I have seen the assassin.'

'Seen him! Who is he? Did you recognize him?' demanded all at once the three men, pressing round him.

'I was returning from Canderol,' said d'Aubian; 'on my way home I passed along the foot-path on the outside of the park. Suddenly I perceived a man letting himself slip down the wall. This excited my suspicions, and I advanced toward him, but at sight of me he instantly took to his heels, and disappeared in the fields. In his stead I only found a cord hooked to the wall. Fearing lest some mishap had befallen Monsieur Gorsay, I clambered over the wall by means of this cord, in order to reach the house more quickly and give the alarm; which I was about to do when I saw your lanterns.'

'And did you recognize him? this robber?' asked one of the domestics.

'No,' replied Arthur, calling to mind the threat of the convict.

'It could only have been Bonnemain who has done this deed,' said Piquet; 'I always mistrusted that sulky wretch.'

One of the men who had been ferretting along the wall, now suddenly raised himself. 'Here is a knife!' said he; 'and there is blood upon it!'

The instrument of murder passed from hand to hand. It was one of those poniards without a sheath, known as Catalonian knives, the blade of which on opening is fastened by a spring. The steel had been carefully wiped, but in the groove of the handle might be seen traces of blood which had not been completely effaced.

'He cannot be far off,' said the head gardener; 'we must track him like a villanous wolf as he is. Come on, boys! let us after him, all hands! But you, Monsieur d'Aubian, will not you come in and console poor Madame Gorsay a little? She is almost distracted. Think what a shock this is to the poor lady! They have sent for the doctor, the priest, and the king's attorney; all is in confusion; but I am sure she will be glad to see you, who are so good a friend of the family.'
