The stranger became thoughtful likewise, and sat for five or ten minutes
looking at the fire in silence. At length he rose and divested himself
of his shawl and great-coat, which (far different from Mr Pinch's) was
a very warm and thick one; but he was not a whit more conversational out
of his great-coat than in it, for he sat down again in the same place
and attitude, and leaning back in his chair, began to bite his nails. He
was young--one-and-twenty, perhaps--and handsome; with a keen dark eye,
and a quickness of look and manner which made Tom sensible of a great
contrast in his own bearing, and caused him to feel even more shy than
usual.

There was a clock in the room, which the stranger often turned to
look at. Tom made frequent reference to it also; partly from a nervous
sympathy with its taciturn companion; and partly because the new pupil
was to inquire for him at half after six, and the hands were getting
on towards that hour. Whenever the stranger caught him looking at this
clock, a kind of confusion came upon Tom as if he had been found out in
something; and it was a perception of his uneasiness which caused the
younger man to say, perhaps, with a smile:

'We both appear to be rather particular about the time. The fact is, I
have an engagement to meet a gentleman here.'

'So have I,' said Mr Pinch.

'At half-past six,' said the stranger.

'At half-past six,' said Tom in the very same breath; whereupon the
other looked at him with some surprise.
