Not only is the premise extraordinarily clever, the pacing of the story is perfect.
A matinee idol, after inhabiting hell for half a century, is given the chance to leave in a very rare offer from on high. The conditions are that he will be reincarnated, will help a group of innocents, and, crucially, will not know anything about the deal.
Cruelly (perhaps), he is put into the body of Nicholas Dismas, a private detective with spina bifida who was abandonned as a newborn, who is contacted by a mother who suspects that her "stillborn" child has, in fact, been kidnapped.
Told in the first person, Others spirals rapidly from an apparent cut and dry PI story into a very disturbing (indeed) tale of extreme "medical malpractice".
If you can stand the deranged ending, this is excellent.
