Flint Rock is fifty-three, retired after thirty years as a professional pilot. He lives alone in San Marcos, Texas. He meets a friend for a drink at the bar of the Menger Hotel next door to the Alamo in San Antonio. Teddy Roosevelt recruited men to follow him up San Juan Hill in Cuba at the Menger Bar. Surrounded by Spanish American War photos, in a warm ambience of aged dark wood, Flint's chat with his friend is interrupted when a strikingly attractive woman with long blond hair lays a business looking card on the table in front of him. Elegantly printed on it: "I have heard how good you are, and I want to meet you." The woman leaves the bar. The card has her name, email address, and phone number.
As it turns out, the woman is a psychiatrist in private practice in Austin, Texas. She has a problem. Someone has tried to kill her, and she has no idea who or why. Flint gets involved when someone tries to kill him because he has communicated with her..
Flint's investigation takes him to the Amalfi coast. He narrowly escapes in the Roman ruins at Pompeii and again nearby in Naples. In a surprise twist, Flint and his psychiatrist friend meet an Indian guru in Athens where a crucial clue is uncovered. The plot grows more complex in the shadow of the Parthenon.
The "angel trumpet" society in Naples mixes mafia dynamics with a Pakistani politician and Latin American geologists in Rome.
