This novel is the second or third of Mr. Catherall’s young adult novels I’ve read, and I’m beginning to get a feel for his style and genre. He reminds me of the adult spy novelists Nevill Shute or Alistair MacLean, or even Helen MacInnes, but a bit more tame with teen protagonists. I would guess that boys ages 13 to 16 would find Catherall’s novels quite intriguing.

This mystery takes place on an impoverished island off the southern coast of the former Yugoslavia. It’s several years post-World War 2, but the people who live on this island are still trying to recover from the war and all of its many depredations and consequences. One of those consequences of war is that our protagonist, Josef Piri, fourteen years old, lives with his grandfather and his mother, all of them believing that Josef’s father died in the war before Josef was born.

One day while Josef and his grandfather are out fishing, a police boat comes alongside to ask if they have seen an escaped fugitive on or near the island. Josef, in fact has and does see the escapee clinging to a rope alongside the police launch, out of sight and desperate to remain so. What is the right thing to do? Remain silent and help the man escape or give him up to the authorities?

The choice Josef makes leads him and his entire island village into quite an adventure. There are guns and hidden treasure and narrow escapes and various people who are not what they seem to be. Josef must draw again and again on his courage and his innovative ideas to protect his family and the other villagers and to understand his heritage as his father’s son.

The story takes place in Communist Yugoslavia in about 1960, and it was published in 1964. The Communist government is far away in this story, and is neither praised nor criticized. The villagers, including Josef and his family, live far from the day to day reach of the government, and their lives continue with very little government interference or help. There are a couple of mentions of government aid to the villagers, but it’s not significant. And the adventure that Josef’s encounter with the police boat and the escaped fugitive brings has little or nothing to do with Communism or Marshal Tito.
