The Secret of the League by Ernest Bramah

Sir John Hampden lived within a stone-throw of the Marble Arch; George Salt had established himself in Westminster; and about midway between the two, in the neighbourhood of Pall Mall, a convenient but quite unostentatious suite of offices had been taken and registered as the headquarters of the Unity League.

The Unity League was a modern organisation that had come into existence suddenly, and with no great parade, within a week of that day when George Salt had forced Hampden to hear what he wished to say, a day now nearly two years ago. The name was simple and commonplace, and therefore it aroused neither curiosity nor suspicion; it was explained by the fact that it had only one object: "By constitutional means to obtain an adequate representation of the middle and upper classes in Parliament," a phrase rendered by the lighter-hearted members colloquially as "To kick out the Socialists. " The Government, quite content to govern constitutionally (in the wider sense) and to be attacked constitutionally (in the narrower sense), treated the existence of the Unity League as a playful ebullition on the part of the milch sections of society, and raised the minimum income-tax to four and threepence as a sedative.
