Book excerpt: Perfect holiday reading from Domenica de Rosa, author of the bestselling Dr Ruth Galloway Mysteries under the pen name Elly Griffiths. A group of would-be authors retreats to Tuscany where they learn more than how to write better. Patricia O'Hara's carefully composed ads for the writers' retreat she runs promise so much. The splendour of the thirteenth century Italian castle and chef Aldo's melanzane never fail to wow the guests, but huge maintenance bills and bad news from the bank mean it's make or break time for the Castello. Each of her seven aspiring authors arrives with the inevitable baggage alongside their unpublished manuscripts. But this August something is different, and soon lifelong spinster Mary is riding on the back of Aldo's vespa, and smouldering odd-job man Fabio has set more than one heart racing. As temperatures rise, the writers gossip, flirt and gently polish their prose by the pool. But with ghosts, scorpions, and some unexpected visitors to contend with, one thing's for sure: neither the Castello, nor Patricia, has ever seen a summer like this.
