Title: A Taste of Ashes - Elizabeth George - book
Summary :
If the fire at the elegant cottage in Springburn, Kent, was almost perfect, the crime was no less so. A bunch of matches, a slow-burning cigarette, and there you have it, a time-delay ignition system within the reach of any amateur. But examination of the scene and the charred body proved that Kenneth Fleming had been murdered first. The murder of a cricket champion whose talent divides England concerns all of London, and therefore Scotland Yard. Linley and Havers investigate, he with his customary Eton alumnus' harshness, she with her feigned timidity. Both too human to judge the atrocious acts they uncover.
