In his more imaginative moments he would create a world in which he was the recognised colleague of Malcolm Sage, the avowed admirer of Miss Norman, and the austere employer of Tims—chauffeurs never took liberties with the hair of their employers, no matter how knut-like it might be worn.

It was with the object of making sure of the first turret of his castle in Spain, that William Johnson devoted himself to the earnest study of what he conceived to be his future profession.

He read voraciously all the detective stories and police-reports he came across. Every moment he could snatch from his official duties he devoted to some scrap of paper, booklet, or magazine. He strove to cultivate his reasoning powers. Never did a prospective client enter the Malcolm Sage Bureau without automatically setting into operation William Johnson's mental induction-coil. With eyes that were covertly keen, he would examine the visitor as he sat waiting for the two sharp buzzes on the private telephone which indicated that Malcolm Sage was at liberty.

It mattered little to William Johnson that error seemed to dog his footsteps; that he had "deduced" a famous pussyfoot admiral as a comedian addicted to drink; a lord, with a ten century lineage, as a man selling something or other; a Cabinet Minister as a company promoter in the worst sense of the term; nothing could damp his zeal.

Malcolm Sage's "cases" he studied as intimately as he could from his position as junior; but they disappointed him. They seemed lacking in that element of drama he found so enthralling in the literature he read and the films he saw.

Malcolm Sage would enter the office as Malcolm Sage, and leave it as
Malcolm Sage, as obvious and as easily recognisable as St. Paul's
Cathedral. He seemed indifferent to the dramatic possibilities of
disguise.

William Johnson longed for some decrepit and dirty old man or woman to enter the Bureau, selling boot-laces or bananas and, on being peremptorily ordered out, to see the figure suddenly straighten itself, and hear his Chief's well-known voice remark, "So you don't recognise me, Johnson—good." There was romance.

He yearned for a "property-room," where executive members of the staff would disguise themselves beyond recognition. In his more imaginative moments he saw come out from that mysterious room a full-blooded Kaffir, whereas he knew that only Thompson had entered.

He would have liked to see Miss Norman shed her pretty brunetteness and reappear as an old apple-woman, who besought him to buy of her wares. He even saw himself being transformed into a hooligan, or a smart R.A.F. officer, complete with a toothbrush moustache and "swish."

In his own mind he was convinced that, given the opportunity, he could achieve greatness as a master of disguise, rivalling the highly-coloured stories of Charles Peace. He had even put his theories to the test.
