|| Spring, 1940. As World War II heats up in England, Tommy and Tuppence Beresford find themselves, initially anyway, at loose ends. It seems that as a forty-something couple, they may be a bit on the aged side to be of much use to British Intelligence. They try to make the best of it with good humor, but yearn to be of service. Over the hill? Not for long. Their sleuthing skills are essential and soon they are enlisted in the cause , independently taking on assumed identities to uncover Nazi informers who imperil the security of their homeland.
