An investigation becomes very complicated when the past lives of two men threaten to catch up with them. A wonderful novel for young readers by internationally renowned author David Grossman.

I was twelve years old when what I'm about to tell you took place. Today, sixteen years later, I still recall the pounding of my heart as I heard the approaching footsteps of the bully of Heidelberg University. Above me on the bed sat Heinrich Rosenthal, a little man, seventy years old, with a big white mane of hair, but under the bed I was very much alone, and I remember thinking in those moments of suspense, Mom's right, maybe I should go out and make friends my own age instead of always hanging around by myself or with weird people like Mr Rosenthal. So begins an intriguing tale of friendship between an extraordinarily beguiling boy and an old man with a past - a history that shapes the plot of "Duel" and cleverly unfurls in the way real stories do between friends. David and Mr Rosenthal are generations apart in age but equally brave, equally stubborn and each as unique for their years as the other.
