Frank Mulholland and Tom Sommerville are both Londoners, and they've been working as British agents with MI6 for several years. They've formed a good relationship and found success in many missions, including the most recent involving the IRA and Russian spies in Achaladair and Glencoe. They even saved the life of the president. During the Cold War year of 1962, Mulholland and Sommerviille work around the picturesque Bridge of Orchy--a small hamlet on the A82 Road, Cononish Glen, and the Glencoe mountain area of Scotland. With the help of their Ground Team Leader John B. Aitken and a few local lads, they keep an eye on the spies and investigate the mystery of unidentified flying machines observed around the Orchy area that emit a high-pitched hissing noise. An adventure thriller set in the picturesque Scotland, Achaladair explores an exciting, fictional world of power, secrets, sex, and danger.
