Kay is on her way to join her brother, whose wife has deserted her child and husband. As an American government official in Mexico, he is currently swamped dealing with subversive forces trying to cause trouble between the two nations.
Trusting a 'Detour' sign too quickly, Kay runs into trouble in Texas.
Complications arise, of course!

International troublemakers; Beautiful women; Gorgeous haciendas; Personal intrigue... all part of what makes this a typical Emily Loring book
