Unfortunately his wife is not feeling hungry and neighbour Donald arrives unexpectedly as the meal is served and takes a large portion with tragic results.

• East of Wimbledon (1993, ISBN 978-0-571-17151-4): Robert Williams passes himself off as a Muslim to get a job at the Wimbledon Independent Islamic Boys Day School.

Twelfth Imam), whose occultation they eagerly await...
