'Even an old man can strike a match and light a fire. Checkley is a malignant old man. He is quite capable of charging you with the job. I wonder he hasn't done it by this time. Remember my case, old man.' Athelstan's face darkened at the recollection. 'Dirt sticks sometimes. Look at me. I am smirched all over.'

'His manner was very odd this morning—insolent and strange. He began to talk mysteriously of the ingratitude of the forger.'

'Why he's actually going to do it! Don't you see—he means that you are the forger?'

'Oh! does he? Very well, Athelstan'—George finished his coffee and got up—'the sooner we find out this mystery of this Edmund Gray the better. Let us seek your tipsy Scholar.'

They walked from Piccadilly to Holborn, turning the thing over and making a dozen surmises. Edmund Gray, twins: Edmund Gray, father and son—father wanting to destroy property, a Socialist; son wanting to steal property, individualist: Edmund Gray cousins—one the mild philosopher, rejoicing in the decay of wealth; the other a bandit, robber and conspirator: Edmund Gray, father and daughter—the young lady of the advanced type, who has not only thrown over her religion but her morals also: Edmund Gray, master and clerk: Edmund Gray under domination of a villain: there was in every situation a noble chance for the imagination. George showed a capacity unsuspected: he should have been a novelist. The hypothesis was always beautiful and admirable: but it wanted one thing—vraisemblance: one felt, even while advancing and defending one, that it was impossible.

They turned into the gateway of the Inn and walked down the passage into the Square. 'Look!' Athelstan caught his companion by the wrist. 'Who is that?'

'Checkley himself. He is coming out of No 22!'

'Yes, out of 22. What is he doing there? Eh? What has he been doing there?'

It was Checkley. The old man walking feebly, with bent head, came out from the entrance of No. 22 and turned northward into Field Court. They waited, watching him, until he left the Square. 'What is he doing there?' asked George again. 'Come. Edmund Gray must be at home. Let us go up.'

They found the outer door shut. They knocked with their sticks: there was no answer.
