Echo of Diana

This is quite an enthralling little low budget British thriller as Betty McDowell starts to investigate the suspicious death of her husband in a plane crash on the Turkish border. Was he a spy? We set out to discover with the help of journalists Clare Owen and Vincent Ball what exactly happened - is he actually dead? Ernest Morris was an old hand at keeping these moving along a-pace and does so adequately here, too, with plenty of double-crosses to keep it interesting. The jungle-drums music is of the time, and no less annoying for that - it is no substitute for taut writing.
