13.  The Oxford Murders is narrated by an Argentinian maths student, describing events that took place when he went to Oxford on a scholarship in 1993. He only tells the story years after the fact,

14.  After hearing of the death of one of the people he knew there; clearly the truth -- or at least the whole story -- about the 'Oxford Series' of murders that happened that summer did not come to light at the time.

16.  Back then the narrator has arranged to room at the house of Mrs. Eagleton while at Oxford, a woman confined to a wheelchair living with her orphaned granddaughter, Beth.

17.  A few weeks after his arrival, Mrs. Eagleton is murdered. The narrator, along with Arthur Seldom, a "legend among mathematicians" -- indeed, "one of the four leading minds in the field of logic" -- finds the body.

18.  When they find the body, Seldom reveals that he came to the house because of a note he had received, announcing: "The first of the series", along with Mrs. Eagleton's name and address, a time, and a symbol drawn on it -- "a neatly drawn circle".

19.  It does turn out to be the first in a series: first there's another suspicious death -- in conjunction with another note --, followed, eventually, by two more occurrences that are obviously continuations of the series.

20.  Several of the key figures in the novel are mathematicians, and the main lead -- the pieces of paper with different symbols on them -- suggest a mathematically based progression.

21.  Among the clever ideas utilised by Martínez is Wttgenstein's finite rule paradox: that for any series you can always find a rule justifying any continuation of the series ("The series 2,4,8, can be continued with the number 16, but also the number 10, or 2007"). And Gödel is, of course, also invoked.

22.  As long as they have only the first murder, message, and symbol they have no idea what comes next. Once there's a second symbol, they can make an educated guess -- and once there's a third they can feel fairly certain about what to expect next.

23.  But Wittgenstein's rule means there's no certainty. The way that Martinez applies these ideas is particularly inspired, making for the very neat idea that underlies the whole plot -- but it still makes for a somewhat awkward murder mystery.

24.  Part of the problem is in the focus on the characters: there's a curious lack of interest in many of the characters, and an evenness of tone as if Martinez did not want to favour one over another (especially among those who are to be seen as suspects).

25.  The failures of presenting the characters fully are most noticeable in the case of the inspector and Beth, but there are several others who are also too briefly and simply presented -- suggestively pushed centre-stage as potential suspects, and then shoved into the background again.

26.  On the other hand, what Martínez does very nicely is to insert smaller stories in the narrative, allowing characters to reveal themselves --

27.  Seldom, in particular, is allowed to open up several times, and these are among the best parts of the book. The narrator's Oxford life is also fairly well presented, including the love affair he embarks on.

28.  The maths is well integrated into the book, and doesn't overwhelm it. This is also the summer of Andrew Wiles solving Fermat's theorem, and Martínez manages to use that fairly well as well.

29.  There's a leisurely pace to the book, but events still unfold too quickly -- the rich material deserves considerably fuller treatment.
