Do Jews think differently?

Sixteen years into a stop-go production saga, I got a call from the director of The Song of Names with a suggested script change. What, said François Girard, if one of the two protagonists was perhaps, er, not Jewish? My reply cannot be repeated. I was, for a minute or so, completely speechless.

My novel, winner of a 2002 Whitbread Award, is the story of two boys bonding in wartime London. One is a refugee violinist from Poland, the other a middle-class kid of average abilities. ‘I am genius,’ says Dovidl to Martin. ‘You are — a bit everything.’ Beyond bomb sites, their friendship is rooted in a common heritage. The bond is savagely betrayed when Dovidl vanishes. Martin spends the rest of his life obsessively in pursuit.

To recast Martin as a non-Jew would, to my mind, undermine the symbiosis and weaken Martin’s desperate search. If they are two peas in a pod they must surely be broadly similar.
