Death of Mr. Dodsley

"Mr. Richard Dodsley, owner of a fine secondhand bookshop on Charing Cross Road, has been found murdered in the cold hours of the morning. He'd been shot in his own office, where few clues remain besides three cigarette ends, two spent matches, and a few books on the shelves which have been rearranged. In an investigation spanning the secondhand bookshops of London and the Houses of Parliament (since an MP's new crime novel, Death at the Desk appears to have some bearing on the case), Ferguson's series sleuth MacNab is at hand to assist Scotland Yard."--from back cover.
