This isn't a novel with a plot in the traditional sense. Instead, it's a detailed medical treatise from 1780. Dr. Andrew Duncan lays out his observations and arguments for using mercury to treat what was then called 'the venereal disease' (syphilis). He structures it like a legal case, presenting evidence from his own practice and other doctors. He describes different methods of administering mercury (ointments, pills, fumigations), documents patient responses, and fiercely defends its use against critics. The 'story' is his relentless campaign to establish a standard, if brutal, protocol in a medical world full of uncertainty and desperate patients.

Why You Should Read It

This book is a raw, unfiltered window into the past. What grabbed me wasn't the medical details, but the human drama between the lines. You can feel Duncan's frustration and his grim determination. He's not a villain; he's a man convinced he's saving lives, even as he details causing intense suffering. Reading his justifications for treatments that we now know were often more harmful than the disease is profoundly thought-provoking. It makes you appreciate modern medicine while questioning what 'standard practice' we defend today that future generations might see as barbaric. It's less about the science (which is outdated) and more about the mindset of an 18th-century healer.

Final Verdict

This is a niche but fascinating read. It's perfect for history buffs, especially those interested in the gritty realities of pre-modern medicine, or for anyone who loves primary sources that show how people really thought. It's not a light read, but it's surprisingly gripping in its own way. If you've ever enjoyed a medical history podcast or wondered what doctors actually did before antibiotics, this short book offers a direct, unvarnished answer. Just be prepared for some graphic descriptions that will make you very glad you live in the 21st century.
