Desrolles shrugged his shoulders, as much as to say, ‘Here is a poor half-cracked fellow labouring under a harmless delusion. I must indulge him.’

‘Well, my dear sir,’ he said presently, stretching his well-worn boots before the hearth, and luxuriating in the warmth of the blazing wood, ‘if this is all you have to say, you might as well have let me get away by the mail.’

‘You deny the identity of John Treverton and Chicot, the caricaturist?’

‘Most emphatically. I have the honour to know both men, and am in a position to state that they are totally distinct individuals—bearing a kind of resemblance to each other in certain broad characteristics—height, figure, complexion—a resemblance that might mislead a man seeing one of the two for a few moments, as you saw Chicot——’

‘How do you know how often I saw Chicot?’

‘I draw my inference from your own conduct. If you had seen him often—if you had seen him more than once—you could not possibly mistake him for Mr. Treverton, or Mr. Treverton for him.’

Edward Clare shrugged his shoulders, and sat looking frowningly at the fire for some moments. Whatever this man Desrolles knew, or whatever he thought, it was evident that there was very little to be got out of him.

‘You are very positive,’ Edward said presently, ‘so I suppose you are right. After all, I can have no desire to identify the husband of a woman I highly esteem with such a fellow as this Chicot. I want only to protect her interests. Married to a scoundrel, what might not be her fate? Perhaps as terrible as that of the dancer.’

Desrolles answered nothing. He was lying back in the rocking chair, resting, his eyes half closed.

‘Have you seen Chicot since his wife was murdered?’ asked Edward, after a pause.
