"Here I could throw it all in a heap and get away!" Looking round once more, with his hand already in his pocket, he noticed against the outer wall, between the entrance and the sink, a big unhewn stone, weighing perhaps sixty pounds.

The other side of the wall was a street.

He could hear passers-by, always numerous in that part, but he could not be seen from the entrance, unless someone came in from the street, which might well happen indeed, so there was need of haste.
He bent down over the stone, seized the top of it firmly in both hands, and using all his strength turned it over.

Under the stone was a small hollow in the ground, and he immediately emptied his pocket into it.
The purse lay at the top, and yet the hollow was not filled up.

Then he seized the stone again and with one twist turned it back, so that it was in the same position again, though it stood a very little higher.
