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

'Nothing special,' Albert admitted.

Simon rose and came towards the piano.

'Let me show you,' he said superiorly. 'You see the cash-desk to the

He's holding his bill in his hand--you can see the corner of it--and
he's got some sort of a parcel under his arm. See?'

'Yes, Mr. Lecoq.'

'Well, doesn't he remind you of somebody?'

'He's rather like old Ravengar, perhaps,' said Albert dubiously.

'You've hit it!' Simon almost shouted. 'It is Ravengar.'

'This man's got no beard.'

'That comes well from a detective, that does!' said Simon scornfully.
'It needn't have cost him more than threepence to have his beard shaved
off, need it?'

'And seeing that this photograph was taken yesterday morning, and
Ravengar fell off a steamer into the Channel more than a week ago!'

'But did he fall off a steamer more than a week ago?'

'He was noticed on board the steamer before she started, and he wasn't
on board when she arrived.'

'Couldn't he have walked on to the steamer with his luggage, and then
walked off again and let her start without him?'

'But why?'

'Suppose he wanted to pretend to be dead?'

'Why should he
