Mary Higgins Clark has invented a recipe that has long made it a success: a young woman faced with the murder of a loved one (here, his father, retired academic who discovered a priceless parchment) difficulties (his mother suffers from Alzheimer ' Altzeimer), a mystery (but where is that famous parchment past?) to four suspects, including an attractive man in love with her, and finally the danger at the end of the novel when his life held by a thread (but where as Zorro, the man in question will deliver it in extremis). Embellish by the presence of recurring characters, sympathetic amateur detectives Alvirah and Willy, add to it by way of spices a good dose of religion (Catholicism) and you'll have the makings of a novel that can keep you going end to end. But it is still necessary that the ingredients are of high quality. Now, in "The Lost Years", the quality has been set aside. The characters do not have thick, not real life. Described in three lines, the four suspects seem longer interchangeable. The plot is farfetched and one wonders why, among other things, the killer blames heroin at the end of the story. The style seems very flat, sentences being only could not be more factual. However, even if you are disappointed (e) we want to know what will happen in the end and we therefore read the novel until the end. But frankly, Mary Higgins Clark seems to have been smaller form when writing this latest installment.
