Mystery, Murders, Motivations and Mathematics.
This books has it all.
The Oxford Murders by Guillermo Martinez is not just a fascinating murder mystery but also a puzzle that captures the reader and keeps you feverishly turning pages until the end.
The story is told from the perspective of an Argentinian mathematics graduate student who has just arrived at Oxford and is enjoying the novelty of English subtleties and a tendency toward reserved silence until this tranquil world is upset by a series of murders. The first murder is of his elderly landlady, Mrs. Eagleton. He discovers her body in her parlor while accompanied by the renowned logician Arthur Seldom. Seldom then reveals that he had received a message with the words, "the first of a series" and the address of Mrs. Eagleton with the time 3 p.m. written beneath. The paper also contained a symbol, a carefully drawn circle in black ink. The beginning of a logic puzzle, the solution to which may be the only clue to stopping the murders.
