This is the story of the greatest scandal inflicted on British servicemen and women in modern times: drug-induced violence and suicide–and an officer determined to find the truth.

It was supposed to be a wonder drug that would save the world from malaria. But soon after Lariam was brought to international markets in the late 1980s, users of this handy, once-a-week pill began to experience shocking side-effects. Yet over the coming decades, as the drug became implicated in ever-increasing acts of unexplained violence, homicide and suicide, the Ministry of Defence continued to force Lariam on tens, or perhaps hundreds, of thousands of unsuspecting people deployed to some of the world’s most dangerous places.

Enduring years of Lariam-induced nightmares, former soldier Andrew Marriott realised something was horribly wrong; not just with the drug itself but with the institutions responsible for its use and safety. So began a journey towards the truth, a truth that vested interests in the United Kingdom and around the globe were determined to conceal.

In a unique exposé of an entirely preventable pharmaceutical disaster, Marriott turns a spotlight on the murky world of clandestine military and industrial research in the United States in which Lariam was developed. With other survivors, including some very courageous women, he undertakes a forensic examination of a scandal extending to the upper echelons of government and the armed forces. A culture of betrayal and dishonour had imperiled those defending our country to the most insidious and silent form of friendly fire.
