This travelling-closet was an exact square, with a window in the middle of three of the squares, and each window was latticed with iron wire on the outside, to prevent accidents in long journeys.
The story, which unfolds on pages latticed like a maths exercise book, is a collaboration with illustrator Joanna Concejo, who has fed and watered the short text so that it blossoms across 48 pages.
The steps and banisters were of oak; the staircase window was high and latticed; both it and the long gallery into which the bedroom doors opened looked as if they belonged to a church rather than a house.
