Plants, Murder and Medical Mysteries by Dr Sandy Primrose is a collection of real-life stories which detail crimes - abduction, rape and murder - and medical mysteries that have been solved using forensic botany. The same expertise has been used to identify the sources of drugs, to authenticate artefacts, to detect food fraud and illegal logging of protected tree species. Agatha Christie's knowledge of poisons is discussed and details are given of a murderer who used one of her stories as a blueprint for his crime. Clues are given to some of the potions described by Shakespeare in his plays and the reader also is warned about plants that they would be wise to avoid.
