A dead writer's alphabet. A living killer's cryptic messages.

When mysterious symbols begin cropping up around Oxford, most dismiss them as bizarre graffiti. But lexicographer Martha Thornhill knows better. She recognizes the symbols from a runic alphabet created by a deceased fantasy writer whose papers she once worked on. When the graffiti is found near the body of a university lecturer, Martha knows this is no publicity stunt.

And when the suspicious death is assumed by police to be a suicide, she's not the only one to have doubts. Called upon to lend their linguistic expertise to the case, Martha and her colleagues begin to unearth a tragedy that extends beyond the ancient walls of the university. As new messages portend more death, it's clear that a spirit of vengeance is stalking the city's streets. Together, they must find who is behind the cryptic messages, before they become the next victims.
