e passed me, within an arm's length, lifted his right forefinger, as in warning, and without a word went on out of the room, though I observed his exit no more than I had observed his entrance.

'Of course, I need not tell you that this was what you will call a hallucination and I call an apparition. That room had only two doors, of which one was locked; the other led into a bedroom, from which there was no exit. My feeling on realizing this is not an important part of the incident.

'Doubtless this seems to you a very commonplace "ghost story" - one constructed on the regular lines laid down by the old masters of the art. If that were so I should not have related it, even if it were true. The man was not dead; I met him to-day in Union Street. He passed me in a crowd.'

Hawver had finished his story and both men were silent. Dr. Frayley absently drummed on the table with his fingers.

'Did he say anything to-day?' he asked - 'anything from which you inferred that he was not dead?'

Hawver stared and did not reply.

'Perhaps,' continued Frayley,' he made a sign, a gesture - lifted a finger, as in warning. It's a trick he had - a habit when saying something serious - announcing the result of a diagnosis, for example.'

'Yes, he did - just as his apparition had done. But, good God! did you ever know him?'

Hawver was apparently growing nervous.
