Peeping out of the window at the back, I was unable to see Sam. My adroit move, I took it, had baffled him. I had left him standing.

It was a quarter of an hour's drive to my rooms, but to me, in my anxiety, it seemed more. This was going to be a close thing, and success or failure a matter of minutes. If he followed my instructions Smith would be starting for the Continental boat-train tonight with his companion; and, working out the distances, I saw that, by the time I could arrive, he might already have left my rooms. Sam's supervision at Sanstead Station had made it impossible for me to send a telegram. I had had to trust to chance. Fortunately my train, by a miracle, had been up to time, and at my present rate of progress I ought to catch Smith a few minutes before he left the building.

The cab pulled up. I ran up the stairs and opened the door of my apartment.

'Smith!' I called.

A chair scraped along the floor and a door opened at the end of the passage. Smith came out.

'Thank goodness you have not started. I thought I should miss you.
Where is the boy?'

'The boy, sir?'

'The boy I wrote to you about.'

'He has not arrived, sir.'

'Not arrived?'
