In the 1980s they received a disastrous cosmetic makeover. Ignoring the fact that the system was coming apart at the seams, lavish artworks were commissioned and left unfinished, stations were closed instead of being repaired, and only a handful of the oldest remained unspoiled. Russell Square was one of the few that survived. Similar in style to the tube at Mornington Crescent, the frontage of crimson tiles, the blue glass canopy and the arched first-floor windows remained intact. The station was largely used by tourists and students staying in the nearby hotels and hostels, so the entrance was always crowded with visitors consulting maps. Mr Gregory, the stationmaster, was a thin, peppery man with a face that, even in repose, made him look like he was about to sneeze. He greeted the two detectives with a decongestion stick wedged up his right nostril. ‘I’m sorry,’ he apologised. ‘My passages get bunged up in dusty atmospheres.’ ‘You picked the wrong job, then, didn’t you?’ said Bryant with a mean laugh.
