This row of shops was the home to the Murder One crime thriller and (former) science fiction bookshop, but they were forced to move into the much smaller former Sliver Moon women's bookshop, due to the rapacious demands of the property developers, dropping their science fiction books in the process.
Murder One bookshop is now located at 76-78 Charing Cross Road, i.e. on the eastern (Covent Garden) side of the road.
Cambridge Circus is the cross roads of the Charing Cross Road (north south) with Shaftesbury Avenue (east west). It is also the fictional setting of "the Circus" - the headquarters buildings of "British Intelligence", as portrayed in the novels (and their resulting films and TV series) of John le Carré, such as the "KGB mole hunt" in Tinker,Tailor, Soldier, Spy
