The Missing Element, A James Becker Mystery

After decades of clandestine government operations, James Becker and his wife Elizabeth return to his childhood home to enjoy a settled retirement in the small Mississippi river town of Red Wing, Minnesota. But settled is a relative term and no matter where Beck goes, intrigue follows. 

When Minneapolis computer genius, Katherine Whitson, disappears under peculiar circumstances, her husband exploits a sympathetic Red Wing acquaintance to enlist Beck’s aid in finding her. As it turns out, Katherine's kidnapping is more complicated than the typical abduction, and the case taxes the Beckers' considerable skills to their limits.
