Including individual novels as well as; Hercule Poirot - One of the most famous fictional characters of all time, the inimitable Belgian private detective is synonymous with waxed moustaches, perfectionism and little grey cells. Poirot would be the first to call himself a great man - he has never been known for his modesty - but with such success in his career, it is difficult to argue with him. Miss Marple - Doesnt look like your average detective. Quite frankly, she doesnt look like a detective at all. But looks can be deceiving... For a woman who has spent her life in the small village of St Mary Mead, Miss Marple is surprisingly worldly. But as she often points out, she has had every opportunity to observe human nature.
