He found himself in a long car.

The double seats on either side were filled with sleepy people.

There was a passage down the middle, and the lamps above shone dimly through dirty glasses.

Trenholme could not immediately see any one like the man who had spoken to him outside, but he did spy out a baby, and, jug in hand, he went and stood a moment near it.
The lady who held the baby sat upright, with her head leaning against the side of the car.

She was dozing, and the baby was also asleep.
