Doctor Frigo
Doctor Frigo is a novel written by Eric Ambler and published in 1974.
Plot
Dr. Ernesto Castillo, known as "Dr. Frigo" due to his detached and unemotional nature, is a young doctor working on the fictional French-Caribbean island of St. Paul-les-Alizés. He lives in exile following the assassination of his father, a leftist revolutionary who led a failed uprising in their unnamed homeland. Castillo spends much of his time with his fiancée, an art dealer of temperamental disposition who descends from the Habsburg lineage.
The recent discovery of oil in Castillo's native country triggers plans for a renewed rebellion by his late father's former comrades. Their leader, a close associate of Castillo’s father, arrives on St. Paul accompanied by conspirators and seeks Castillo’s medical expertise for mysterious neurological symptoms. They intend to enlist Castillo as the symbolic head of the insurgency because of his heritage.
Upon examination, Castillo identifies the leader as suffering from early-stage amyotrophic lateral sclerosis (ALS), a progressive and incurable disease leading to paralysis. As the illness advances, the conspirators recognize that the success of their revolution hinges on Castillo stepping in to replace their deteriorating leader.
Simultaneously, agents from the local government coerce Castillo into monitoring the conspirators during his medical visits. Caught between governmental pressure and his professional ethics, he reluctantly aids the revolutionaries. Gradually, he begins to suspect that his patient may have been responsible for orchestrating his father’s assassination.
The group eventually returns to their homeland to initiate the rebellion. An insider confirms Castillo’s suspicion that the patient ordered the murder following the initial failed uprising. Castillo confronts a moral quandary: whether to seek vengeance against the patient—thereby breaching medical ethics and legal boundaries—or allow the disease to take its natural course.
Before he can decide, the patient is betrayed and killed by one of his own followers. With this burden lifted, Castillo resumes his medical career and life with his fiancée.
Reception
This novel is regarded as one of Ambler’s finest achievements. Kirkus Reviews described it as "urbane, amusing, cautionary and threateningly urgent."
