The visit was fortuitous, the decision impulsive and he was later to look back on that afternoon as one of life’s bizarre coincidences which, although occurring more frequently than reason would expect, never fail to surprise. He had left the Home Office building in Queen Anne’s Gate at two-thirty after a long morning meeting only briefly interrupted by the usual break for brought-in sandwiches and indifferent coffee, and was walking the short distance back to his New Scotland Yard office. He was alone; that too was fortuitous. The police representation at the meeting had been strong and Dalgliesh would normally have left with the Assistant Commissioner, but one of the Under Secretaries in the Criminal Policy Department had asked him to look in at his office to discuss a query unrelated to the morning’s business, and he walked unaccompanied. The meeting had produced the expected imposition of paperwork and as he cut through St. James’s Park underground station into Broadway he debated whether to return to his office and risk an afternoon of interruptions or to take the papers home to his Thames-side flat and work in peace.
