The Green Empress — Elizabeth Cadell

The Green Empress coaches specialised in taking clients of wealth or importance across Europe in luxury. When Angus Graham became “liaison officer” for one of these coaches he did so lightheartedly, but the dangers and difficulties of the journey were only compensated for by the charming presence of Lord Lorrimer's daughter Angela. The mysterious happenings and complications shows Angus that things aren't always as they seem.
