Elsa Longhurst beamed: “It is a relief to be with people who share our views. We cannot, of course, mention a word about our operation, Mrs Butters. Suffice to say, it will help end this terrible fratricidal war. We will not risk your security by staying here but a brief message on your wireless could make the difference between our success and failure.”
