The Hole in the Wall by Arthur Morrison

I had never seen either of the partners in the firm of Viney and Marr: as I may have said already. On the day after the man was stabbed at our side door I saw them both.

That morning the tide was low, and Hole-in-the-Wall Stairs ended in a causeway in the midst of a little flat of gravel and mud. So, since the mud was nowhere dangerous, and there was no deep water to fall into, I was allowed to go down the steps alone and play on the foreshore while Grandfather Nat was busy with his morning's affairs; the two or three watermen lying by the causeway undertaking to keep an eye on me. And there I took my pleasure as I would, now raking in the wet pebbles, and heaving over big stones that often pulled me on to all-fours, now climbing the stairs to peep along the alley, and once or twice running as far as the bar-parlour door to report myself to Grandfather Nat, and inform him of my discoveries.
