It is May in Aberystwyth, and the mayoral election campaign - culminating in the traditional boxing match between candidates - is underway. Sospan the ice-cream seller waits in his hut for souls brave enough to try his latest mind-expanding new flavour, and Louie Knight, Aberystwyth's only Private Detective, receives a visit from a mysterious stranger called Raspiwtin asking him to track down a dead man.
Twenty-five years ago Iestyn Probert was hanged for his part in the notorious raid on the Coliseum cinema, but shortly afterwards he was seen, apparently alive and well, boarding a bus to Aberaeron. Did he miraculously evade the hangman's noose? Or could there really be substance to the rumours that he was resuscitated by aliens? />
Now, as strange lights are spotted in the sky above Aberystwyth and a farmer claims to have had a close encounter with a lustful extraterrestrial, Iestyn Probert has been sighted once again. But what does Raspiwtin want with him? And why does Louie's investigation arouse unwelcome interest from a shadowy government body and a dark-suited man in a black 1947 Buick?
