Before reaching Knightsbridge, Mr Verloc took a turn to the left out of the busy main thoroughfare, uproarious with the traffic of swaying omnibuses and trotting vans, in the almost silent, swift flow of hansoms. Under his hat, worn with a slight backward tilt, his hair had been carefully brushed into respectful sleekness; for his business was with an Embassy. And Mr Verloc, steady like a rock—a soft kind of rock—marched now along a street which could with every propriety be described as private. In its breadth, emptiness, and extent it had the majesty of inorganic nature, of matter that never dies. The only reminder of mortality was a doctor’s brougham arrested in august solitude close to the curbstone. The polished knockers of the doors gleamed as far as the eye could reach, the clean windows shone with a dark opaque lustre. And all was still. But a milk cart rattled noisily across the distant perspective; a butcher boy, driving with the noble recklessness of a charioteer at Olympic Games, dashed round the corner sitting high above a pair of red wheels. A guilty-looking cat issuing from under the stones ran for a while in front of Mr Verloc, then dived into another basement; and a thick police constable, looking a stranger to every emotion, as if he too were part of inorganic nature, surging apparently out of a lamp-post, took not the slightest notice of Mr Verloc. With a turn to the left Mr Verloc pursued his way along a narrow street by the side of a yellow wall which, for some inscrutable reason, had No. 1 Chesham Square written on it in black letters. Chesham Square was at least sixty yards away, and Mr Verloc, cosmopolitan enough not to be deceived by London’s topographical mysteries, held on steadily, without a sign of surprise or indignation. At last, with business-like persistency, he reached the Square, and made diagonally for the number 10. This belonged to an imposing carriage gate in a high, clean wall between two houses, of which one rationally enough bore the number 9 and the other was numbered 37; but the fact that this last belonged to Porthill Street, a street well known in the neighbourhood, was proclaimed by an inscription placed above the ground-floor windows by whatever highly efficient authority is charged with the duty of keeping track of London’s strayed houses. Why powers are not asked of Parliament (a short act would do) for compelling those edifices to return where they belong is one of the mysteries of municipal administration. Mr Verloc did not trouble his head about it, his mission in life being the protection of the social mechanism, not its perfectionment or even its criticism.
