This is the debut novel for author Rosen along with his protagonist, Henri Poincaré, and although it was quite a fete it has not as yet been followed up with a sequel.
A bomb has gone off in the Amsterdam hotel room of the highly regarded mathematician, James Fenster. Poincaré and his side-kick Serge Laurent begin the detection work – the forensics, the interviews. There are several likely suspects, Fenster’s ex-fiance, a colleague, left-wing politicos, a banker, others. A huge aspect to the plot is the evangelist belief that Christ will return in just a few days. And part of the detection consists of the patterns and formulas used by the mathematician.
