"No, sir, I can't," he replied; and he went out to see to the carriage.
I slipped into a bag an assortment of emergency drugs and a few diagnostic instruments, turned down the gas and passed out through the surgery. The carriage was standing at the kerb, guarded by the coachman and watched with deep interest by the bottle-boy. I viewed it with mingled curiosity and disfavour. It was a kind of large brougham, such as is used by some commercial travellers, the usual glass windows being replaced by wooden shutters intended to conceal the piles of sample-boxes, and the doors capable of being locked from outside with a railway key.
As I emerged from the house, the coachman unlocked the door and held it open.
"How long will the journey take?" I asked, pausing with my foot on the step.
The coachman considered a moment or two and replied:
"It took me, I should say, nigh upon half an hour to get here."
This was pleasant hearing. A half an hour each way and a half an hour at the patient's house. At that rate it would be half-past ten before I was home again, and then it was quite probable that I should find some other untimely messenger waiting on the doorstep. With a muttered anathema on the unknown Mr. Graves and the unrestful life of a locum tenens, I stepped into the uninviting vehicle. Instantly the coachman slammed the door and turned the key, leaving me in total darkness.
