Then Mrs. Knight moved the key of Henry 's door from the inside to the outside ; she was always afraid lest he might lock himself in and be seized with a sudden and fatal illness . Then the women dispersed , and Aunt Annie came down to the dining-room , and in accents studiously calm -LRB- as though the preparation of Henry 's bath was the merest nothing -RRB- announced : ` Henry dear , your bath is waiting . ' And Henry would disappear at once and begin by mixing his bath , out of the ewers , the kettles , and the saucepan , according to a recipe of which he alone had the secret . The hour would be about nine o'clock , or a little after . It was not his custom to appear again . He would put one kettle out on an old newspaper , specially placed to that end on the doormat in the passage , for the purposes of Sunday 's breakfast ; the rest of the various paraphernalia remained in his room till the following morning . He then slept the sleep of one who is aware of being the nation 's backbone .
