Other books

In The Matter of the Heart, I trace the extraordinary story of how surgeons first dared to operate on the human heart — once thought beyond the reach of medicine. Through eleven remarkable operations, I explore the risks, rivalries and moments of brilliance that transformed the heart from a symbol of life into a site of hope.

From self-surgery to spontaneous combustion, The Mystery of the Exploding Teeth reveals the gruesomely funny side of medicine they never taught at medical school. This collection of extraordinary curiosities brings history’s most bizarre case notes vividly — and hilariously — back to life.
