Oxford, 1851. A murderer is loose. Edgar Allan Poe has seven days to catch him-or hang.
When a brutal murder rocks Oxford, visiting American author Edgar Allan Poe is arrested and sentenced to death. The evidence is overwhelming. Poe knows he is innocent. Unfortunately, no one else does.
His only hope is an unlikely young ally: Charles Dodgson, a brilliant Oxford mathematician with an obsession for logic, puzzles, and problems that have no obvious solution. Someday, the world will know him as Lewis Carroll. For now, he is the one man willing to believe Poe's story.
Together, they race through the shadowy colleges of Oxford, following a trail of coded manuscripts, secret societies, vanished evidence, and impossible crimes. But each answer leads to a more disturbing question-and someone is determined to make sure Poe never reaches the truth.
Then another body appears.
As the clock runs down, Poe and Dodgson discover that the murders are part of a mystery far stranger than either could have imagined. A mystery involving a locked room that could not have been entered, a message that could not have been written, and a killer who always seems to be one step ahead.
Seven days. One impossible murder. Two extraordinary minds.
And if Poe and Dodgson cannot solve the mystery in time, the most famous mystery writer of the age will become its final victim.
