What happened
The lottery was honest; the list it produced was not. Juno and Tess, the interns who typed in the results, swapped eleven genuine winners for names from a waiting list of buyers. Lionel and Olive, two private patients with many wealthy friends, sold those places at £50,000 each over dinners in their suites; Sadie, at reception, booked the buyers in under the real winners' appointment slots; and Frank, Nora and Ruby, on security, politely escorted the true winners off the premises when they arrived asking why nobody had called. One of them, a retired headmistress, went straight to the newspapers.
