A Prefect’s Uncle by P. G. Wodehouse

Marriott walked into the senior day-room, and, finding no one there, hurled his portmanteau down on the table with a bang. The noise brought William into the room. William was attached to Leicester’s House, Beckford College, as a mixture of butler and bootboy. He carried a pail of water in his hand. He had been engaged in cleaning up the House against the conclusion of the summer holidays, of which this was the last evening, by the simple process of transferring all dust, dirt, and other foreign substances from the floor to his own person.
