Monte Irvin, alderman of the city and prospective Lord Mayor of London, paced restlessly from end to end of the well-appointed library of his house in Prince's Gate. Between his teeth he gripped the stump of a burnt-out cigar. A tiny spaniel lay beside the fire, his beady black eyes following the nervous movements of the master of the house. At the age of forty-five Monte Irvin was not ill-looking, and, indeed, was sometimes spoken of as handsome. His figure was full without being corpulent; his well-groomed black hair and moustache and fresh if rather coarse complexion, together with the dignity of his upright carriage, lent him something of a military air. This he assiduously cultivated as befitting an ex-Territorial officer, although as he had seen no active service he modestly refrained from using any title of rank.
