It has taken decades for the cruel human experiments perpetrated by imperial Japan to come into sharp relief. Jeanne Guillemin’s book is both a fascinating background account of the Tokyo war crimes trial and a dispiriting tale of moral compromise. Her meticulous reconstruction of this failure of justice should stand as a worthy if long-delayed memorial to the victims.
