At last a porter came, and looked up and down the line.

Apparently he saw no obstruction, for he proceeded to lower the signal.

We rose and paced to and fro, with valorously concealed agitation.

A trap dashed along the white road, and some one ran, breathlessly, up the stairs.

He seemed a little surprised at the trio which awaited him.

"I thought you had two cases in Bonnor," I observed, with a piercing glance.

The doctor looked away, but did not reply, and I forbore to press the point.

Far down the line shone a cloudlet of white smoke and the gleam of brass through the dust.

"Becklington, Harrowley, Borcombe and Hoxford train," roared the porter, apparently as a reminder to the station-master, for there were no passengers.
