ACT I

Great George Street, Westminster, is the address of Doyle and Broadbent, civil engineers. On the threshold one reads that the firm consists of Mr Lawrence Doyle and Mr Thomas Broadbent, and that their rooms are on the first floor. Most of their rooms are private; for the partners, being bachelors and bosom friends, live there; and the door marked Private, next the clerks' office, is their domestic sitting room as well as their reception room for clients. Let me describe it briefly from the point of view of a sparrow on the window sill. The outer door is in the opposite wall, close to the right hand corner. Between this door and the left hand corner is a hatstand and a table consisting of large drawing boards on trestles, with plans, rolls of tracing paper, mathematical instruments and other draughtsman's accessories on it. In the left hand wall is the fireplace, and the door of an inner room between the fireplace and our observant sparrow. Against the right hand wall is a filing cabinet, with a cupboard on it, and, nearer, a tall office desk and stool for one person. In the middle of the room a large double writing table is set across, with a chair at each end for the two partners. It is a room which no woman would tolerate, smelling of tobacco, and much in need of repapering, repainting, and recarpeting; but this is the effect of bachelor untidiness and indifference, not want of means; for nothing that Doyle and Broadbent themselves have purchased is cheap; nor is anything they want lacking. On the walls hang a large map of South America, a pictorial advertisement of a steamship company, an impressive portrait of Gladstone, and several caricatures of Mr Balfour as a rabbit and Mr Chamberlain as a fox by Francis Carruthers Gould.

At twenty minutes to five o'clock on a summer afternoon in 1904, the room is empty. Presently the outer door is opened, and a valet comes in laden with a large Gladstone bag, and a strap of rugs. He carries them into the inner room. He is a respectable valet, old enough to have lost all alacrity, and acquired an air of putting up patiently with a great deal of trouble and indifferent health. The luggage belongs to Broadbent, who
