Only the Innocent is Rachel Abbott's first book and it's hard to tell. This is a great story which weaves itself round a few central characters. Lord Hugo Fletcher is murdered and Detective Chief Inspector Tom Douglas is brought in to investigate. Whilst on the surface this is a police procedural, it's more of a tale of the people close to Hugo and why he wasn't the wonderful person his public persona was.
At 471 pages this was a big chunk of a book and took me quite a time to read. On the whole I didn't think it dragged, though.
I couldn't even guess whodunnit right until the end
