Just as he was a.s.suming his waistcoat, Simon entered.

'Mr. Galpin, sir.'

'And who the d---l is Mr. Galpin?' asked Hugo.

'Mr. Galpin is the gentleman who saved your life yesterday, sir,' said Simon with admirable sangfroid. 'He has called for a hundred pounds.'

'Show him in here immediately,' said Hugo.

Mr. Galpin appeared in the dressing-room, looking more than ever like an extremely successful commercial traveller. Hugo could not think of any introductory remark worthy of the occasion.

'I needn't say how grateful I am,' Hugo began.

'Certainly you needn't,' said Mr. Galpin. 'I understand. I've been under lock and key myself.'

'I should offer you more than this paltry sum,' said Hugo, with a smile, 'but I know, of course, that a man like you can always obtain all the money he really wants.'

Mr. Galpin smiled, too.

'However,' continued Hugo, detaching his watch from his waistcoat, 'I will ask you to take something that you can't get elsewhere. This is the thinnest watch in the world. Breguet, of the Rue de la Paix, Paris, made it specially for me. It is exactly the same size as a five-shilling piece. It repeats the quarters, shows the time in four cities, and does practically everything except tell the weather and the political party in power. It has one drawback. Only Breguet can clean it, and he will charge you five guineas for the job, besides probably having you arrested for unlawful possession. I must write to him. Such as it is, accept it.'

The golden, jewelled toy was offered and received with a bow. The practised hands of Mr. Galpin had opened the case in two seconds.

'How do you regulate it?' demanded Mr. Galpin, staring at the movement.

'You don't,' said Hugo proudly; 'it never needs it.'

Mr. Galpin stood corrected.

'If there's anything in my line I can do for you at any time, sir,' said he.

Hugo pondered.

Mr. Galpin put the watch in his waistcoat-pocket, and, tearing the hundred-pound note in two halves, placed one half in the left breast pocket of his coat, and the other half in the right breast pocket of his coat.

'Could you have opened that vault,' Hugo asked, 'if both keys had been lost?'

'No, sir, I could not. It's such people as you who are ruining my profession, sir.'

'You think the vault is impregnable?'

'Yes, sir,' said Mr. Galpin. 'I should say its name was just about as near being Gibraltar as makes no matter.'

'I was only wondering,' Hugo mused aloud, 'only wondering.... Ah, well, I won't trouble you with my fancies.'

'As you wish, sir. Good-bye.'

'Good-bye, Mr. Galpin. And thank you!'

'Thank _you_, sir,' said Mr. Galpin, and disappeared.

'Simon,' Hugo ordered immediately afterwards, handing Simon the token, 'run down and get me the best gold watch in the place.'

Throughout the morning Hugo's thoughts were far away. Most frequently they were in Belgium, but now and then they paid a strange incomprehensible visit with Ravengar to the vault.

While he was lunching under the dome, Albert Shawn came in with the early edition of the _Evening Herald_, containing a prominent item headed, 'Feared Suicide of Mr. Louis Ravengar.' The paper stated that Mr. Ravengar had gone to Dover on the previous evening, had been seen to board the Calais steamer, and had been missed soon after the boat had left the harbour. His hat, umbrella, rug, and bag had been found on deck. As the night was quite calm, there could be no other explanation than that of suicide. The _Evening Herald_ gave a sympathetic biography of Mr. Ravengar ('one of our proprietors'), and attributed his suicide to a fit of depression caused by the entirely groundless rumours which had circulated during the late afternoon connecting him with the scandalous disturbances at Hugo's sale.

Hugo dropped the organ of public opinion.

'H'm!' he observed to Albert.

'I'm not surprised, sir,' said Albert.

'Aren't you?' said Hugo. 'Then, there's nothing more to be said.'

Since Louis Ravengar had certainly been talking with Hugo that selfsame morning, it was obviously impossible that he should have committed suicide in the English Channel some twelve hours earlier. Why, then, had he arranged for this elaborate deception to be practised? What was his scheme? His voice through the telephone had been so quiet, so resigned, so pathetic; only towards the end had it become malevolent.

Hugo perceived that he must go down to the vault. No! He dared not go himself. The sight of that vault, after yesterday's emotions, would surely be beyond his power to bear!

'Albert,' he said, 'go to the Safe Deposit.'

'Yes, sir.'

'And inquire if anyone named--'

Hugo stopped.

'Named what, sir?'

'Never mind. I'll go myself. By the way,' he said, 'I must run over to Belgium to-night. Perhaps I may take you with me.'

'Don't forget the inquest on Bentley to-morrow, sir. You'll have to attend that.'

Hugo made a gesture of excessive annoyance. He had forgotten the inquest.

'Take this telegram,' he said, suddenly inspired; and he scribbled out the following words: 'Darcy, 16, Boulevard des Italiens, Paris. Please come instantly; urgent case.--HUGO, London.'

'At any rate, I've made a beginning,' he murmured when Albert had gone.

'I can find out all that is to be known about Camilla from Darcy--if he comes. I wonder if he'll come. He'd better.'

And then, collecting his powers of self-control, he went slowly down to the Safe Deposit, and entered those steely and dreadful portals.

'Getting on all right?' he said to the newly-installed manager, a young man with light hair from the counting-house.

'Oh yes, Mr. Hugo.'

'Any new customers?'
