At the request of a Foreign Office friend of Richard\'s they agree to serve as messengers to a man who has been involved in rescue work and anti-Nazi espionage, a man who now seems to have gone missing. Their qualifications? Next to nothing except for Richard\'s superb memory and the fact that they look so very innocent. Across a continent on the brink of war from Paris to Innsbruck and beyond Richard and Francis travel ever deeper into danger.
Ride a Pale Horse (1984, 1st edition): When journalist Karen Cornell is invited to a peace conference in Prague, she only goes on the understanding that she will be granted a valuable interview.

With the papers safely in the hands of Peter Bristow, the one CIA man Karen can trust, she is sure her part in the drama is over, but soon she is pulled into an astonishing web of blackmail, assassination and treason at the highest level. There is a mole in the CIA and it is Bristow’s job to find it, as well as protecting Karen from an unknown enemy.Three in One: Agent in Place; The Hidden Target & Cloak of Darkness (Galahad Books, 1993)
