The Oxford Brotherhood: Guillermo Martinez

Mathematics student G is trying to resurrect his studies, which is proving difficult as he finds himself - and not for the first time - drawn into investigating a series of mysterious crimes.

When Kristen, a researcher hired by the Lewis Carroll Brotherhood, makes a startling new discovery concerning pages torn from Caroll's diary, she hesitates to reveal to her employers a hitherto unknown chapter in his life. Oxford would be rocked to its core if the truth about Lewis Carroll's relationship with Alice Liddell - the real Alice - were brought to light.

After Kristen is involved in a surreal accident and members of the Brotherhood are anonymously sent salacious photographs of Alice, G joins forces with Kristen as they begin to realise that dark powers are at work. More pictures are received, and it becomes clear that a murderer is stalking anyone who shows too much interest in Carroll's life.

G must stretch his mathematical mind to its limits to solve the mystery and understand the cryptic workings of the Brotherhood. Until then, nobody, not even G, is safe. A thrilling novel from the author of The Oxford Murders, inspired by true, strange stories from Caroll's life, The Oxford Brotherhood is sure to make you curiouser and curiouser.
