How are the terrible death of a black prostitute and the murder of a modest London librarian related? Why did the London police need to resort to the help of voodoo magic specialists? Homicide detective Anna Travis and her former boss and lover Jimmy Langton are forced to put together two, three... four completely independent, seemingly independent cases! Despite the brutal cruelty of the criminals who almost sent Langton to the next world, despite the ingenuity of a gang of illegal immigrants, human and drug traffickers, stubborn police still manage to tie all the threads together. Clean work!
