‘I want to see Mrs. Tudor,’ said Hugo.

‘Well, she ain’t in at the moment,’ replied the man.

‘Excuse me,’ Hugo corrected him, ’I saw her enter a minute ago with her latchkey.’

‘No, you didn’t,’ the man persisted.  ’I’m the landlord of this house, and I’ve been in my room at the back, and nobody’s come in this last half-hour, for I can see the ‘all and the stairs as I sits in my chair.’

‘Wait a moment,’ said Hugo; and he retreated to the kerb, in the expectation of being able to descry Camilla’s light in the fifth story.

‘Oh, you can look,’ the landlord observed loftily, divining his intention; ‘I warrant there’s no light there.’

And there was not.

‘Perhaps you’ll call again,’ said the landlord suavely.

‘I suppose you haven’t got a room to let?’ Hugo demanded, fumbling about in his brain for a plan to meet this swift crisis.

‘I can’t tell you till my wife comes home.’

‘And when will that be?’

‘That’ll be to-morrow.’

The door was banged to.  Hugo rang again, wrathfully, but the door remained obstinate.

‘Come in,’ said Simon grandly, in response to a knock.

He was seated in his master’s chair in the dome, which was lit as though for a fete.  The clock showed the hour of nine.

Albert entered.

‘Oh, it’s you, is it?’ exclaimed Albert.  ‘Where’s the governor?’

’I don’t know where he is.  He was in his office at something to seven, having an interview with Mrs. Tudor.  Since then—­’

Simon raised his eyebrows, and Albert expressed a similar sentiment by means of a whistle.

‘Then, you’ve been telephoning on your own for me to come up?’

‘Yes.’

‘It’s like your cheek!’ Albert complained, calmly perching himself on the top of the grand piano.

’Perhaps it will be.  I regret to tear you from your fireside, Alb, but I wish to consult you on a matter affecting the governor.’

‘Go ahead, then,’ said Albert.  ’There’s been enough talk about the governor to-day downstairs, I should hope.’

‘You mean in reference to Mrs. Tudor’s reappearance?’

‘Yes.’  Albert imitated Simon’s carefully enunciated periods.  ’I do mean in reference to Mrs. Tudor’s reappearance.  By the way, what the deuce are you burning all these lights for?’

‘I was examining this photograph,’ said Simon, handing to his brother a rather large unmounted silver-print photograph which had lain on his knees.

‘What of it?’ Albert asked, glancing at it.  ’Medical and Pharmaceutical Department, isn’t it?  Not bad.’

’We’re having a new series of full-plate photographs done for the next edition of the General Catalogue,’ said Simon, ’and this is one of them.  It contains forty-five figures.  It was taken yesterday morning by that Curgenven flashlight process that we’re running.  Look at it.  Don’t you see anything?’
