I fitted the headlamp beam defelectors to the letter. The first lot ended up flapping & the second blew off entirely, which resulted in us getting untold grief from other motorists and almost being arrested by the French Police! Avoid these at all costs & buy another make (any make has to be better than this). Unfortunately 1 star is the lowest rating I can give.
Although slightly fragmentary in places, this fourth instalments ratchets up the mystrey until it gets to the last third of the book when it hurtles breathlessly to a stunning conclusion. An excellent TV series but the books are so much better.
