A Codex of Metal

Edinburgh 1787. How many chemists does it take to solve a murder?

Elizabeth Fulhame is having a hard time convincing the scientific establishment of Georgian Edinburgh to take her amateur chemistry research and magical experimentation seriously. Just when she thinks she's earning the respect of its two most prominent luminaries - Dr Joseph Black and Dr William Cullen - the three of them are implicated a shocking murder.

It's bad enough that all three were ambivalent at best about the deceased. But a bigger conspiracy is afoot in Edinburgh, with them now caught in the middle. Can Fulhame, Black and Cullen set aside their differences and track down the culprit before destruction is unleashed?

Only Murders In The Building meets the gritty streets of 18th century Edinburgh in this thrilling conclusion to the Edinburgh Doctrines series.
