still did not realise this himself. He was positively going now for a
"rehearsal" of his project, and at every step his excitement grew more
and more violent.

With a sinking heart and a nervous tremor, he went up to a huge house
which on one side looked on to the canal, and on the other into the
street. This house was let out in tiny tenements and was inhabited by
working people of all kinds--tailors, locksmiths, cooks, Germans of

There was a continual coming and going through the two gates and in the
two courtyards of the house. Three or four door-keepers were employed on
the building. The young man was very glad to meet none of them, and
at once slipped unnoticed through the door on the right, and up the
staircase. It was a back staircase, dark and narrow, but he was familiar

"If I am so scared now, what would it be if it somehow came to pass that
I were really going to do it?" he could not help asking himself as he
reached the fourth storey. There his progress was barred by some porters
who were engaged in moving furniture out of a flat. He knew that the
flat had been occupied by a German clerk in the civil service, and his
family. This German was moving out then, and so the fourth floor on this
staircase would be untenanted except by the old woman. "That's a good

woman's flat. The bell gave a faint tinkle as though it were made of
tin and not of copper. The little flats in such houses always have bells
that ring like that. He had forgotten the note of that bell, and now
its peculiar tinkle seemed to remind him of something and to bring it
clearly before him.... He started, his nerves were terribly overstrained
