From a review by "Drew Brainiard" on Amazon.com:

Seventeen-year old Alan Tarr lies in an abandoned beach house,his legs in casts, waiting for the man who tried to kill him....BACKTRACK is beautifully written with fully-realized (memorable) characters, exquisitely evoked mood, and biting humor. Written in the days when authors didn't have to pad with extraneous subplots and other filler, every word counts in this little gem of a book; if I had to pick my favorite Hansen mystery it would be BACKTRACK, and the story of Alan Tarr who comes to Hollywood to discover what became of his father....Effectively alternating between 'Now' and 'Then' chapters, we follow Alan's journey of discovery...to the inevitable showdown.
