Tess M. Calloway is the author of the Zoe Blaise Mysteries, a series of corporate conspiracy thrillers where cosmetic science, forensic accounting, deception and intrigue collide.
Drawing on more than three decades in cosmetic science and claims, Tess brings real scientific and industry knowledge to the fictional world of Zoe Blaise — exploring what can happen when evidence, money, ambition, and influence become entangled.
Originally from Wales, and now living in Germany, Tess has been interviewed on BBC Radio, Talk Radio Europe and Yellow Shelf, and writes about the science and ideas behind her fiction through Deadly Cosmetic Science on LinkedIn and Deadly Cosmetic Conspiracies on Substack.
