Engleby - Sebastian Faulks

The unreliable narrator is a potent device and in “Engleby,” Faulks puts it to work to make an adrenalized detective of the reader.
 
His shrewd first-person protagonist is as compellingly interesting as he is disturbing, because you just don’t know what he might do next.
 
It’s a book unlike anything that Faulks has written, a superb crime thriller.
