This is just like the first three books in the Martin Beck detective series but only better with a gripping plot and twists and turns that make you suspect that the wrong police colleague has been killed in the opening chapter and that the wrong sort of crime has been committed for much of the first half of the book.
It is only when the connection is made by Beck and colleagues with the work the dead policeman might have been engaged with, that things start to become slightly clearer and the pace increases. Linking the current bus murder with an unsolved murder from almost two decades earlier suddenly makes things a great deal more interesting and complicated.
Characters suddenly appear that like to do a lot of unusual laughing that also tips you the wink that things are heading in the right direction.
