Upperdown by David Brennan

David Brennan's debut novel is a dark reimagining of 'The Pied Piper of Hamelin'.

Things in the town of Upperdown are not as they seem. The Professor struggles with his devotion to proving the Riemann Hypothesis and he walks the streets seeking a solution whilst battling his own deeper preoccupations.

The appearance of a stranger in town, the Piano Man, leads to the resolution of the rat infestation but when the town's children start to go missing it is clear something darker has been set in motion.
