‘Prompt?’ smiled the doctor, shaking hands, and removing his overcoat with fatigued gestures.

’Yes; you must have caught the 4 p.m. express, and come via Folkstone and Boulogne.’

‘I did,’ said Darcy.

‘And yet I expect you didn’t get my telegram till after two o’clock.’

’I have received no telegram from you, my dear Mr. Hugo.  It had not arrived when I left.’

‘Then your presence here to-night is due to a coincidence merely?’

‘Not at all,’ said Darcy; ’it is due to an extreme desire on my part to talk to you.’

‘The desire is mutual,’ Hugo answered, gently insisting that Darcy should put away his cigarettes and take a Muria.  ‘Dare I ask—­’

Darcy had become suddenly nervous, and he burst out, interrupting Hugo: 

’The suicide of Mr. Ravengar was in this morning’s Paris papers.  And I may tell you at once that it’s in connection with that affair that I’m here.’

‘I also—­’ Hugo began.

‘I may tell you at once,’ Darcy proceeded with increasing self-consciousness, ’that when I had the pleasure of meeting you before, Mr. Hugo, I was forced by circumstances, and by my promise to a dead friend, to behave in a manner which was very distasteful to me.  I was obliged to lie to you, to play a trick on you—­in short—­well, I can only ask you for your sympathy.  I have a kind of a forlorn notion that you’ll understand—­after I’ve explained, as I mean to do—­’

‘If you refer to the pretended death of Tudor’s wife—­’ said Hugo.

‘Then you know?’ Darcy cried, astounded.

‘I know.  I know everything, or nearly everything.’

‘How?’ Darcy retreated towards the piano.

‘I will explain how some other time,’ Hugo replied, going also to the piano and facing his guest.  ’You did magnificently that night, doctor.  Don’t imagine for a moment that my feelings towards you in regard to that disastrous evening are anything but those of admiration.  And now tell me about her—­about her.  She is well?’

Hugo put a hand on the man’s shoulder, and persuaded him back to his chair.

‘She is well—­I hope and believe,’ answered Darcy.

‘You don’t see her often?’

‘On the contrary, I see her every day, nearly.’

‘But if she lives at Bruges and you are in Paris—­’

‘Bruges?’

‘Yes; Place Saint-Etienne.’

Darcy thought for a second.

‘So it’s you who have been on the track,’ he murmured.

Hugo, too, became meditative in his turn.

‘I wish you would tell me all that happened since—­since that night,’ he said at length.

‘I ask nothing better,’ said Darcy.  ’Since Ravengar is dead and all danger passed, there is no reason why you should not know everything that is to be known.  Well, Mr. Hugo, I have had an infinity of trouble with that girl.’

Hugo’s expression gave pause to the doctor.
