Espionage, state secrets, cyber security and senile dementia – what a mix, drawn together with drama and tension by Joan Edwards in her A Most Careless Death. The drama unfolds with several central characters moving in and out of the limelight. It is quite difficult to really ascertain who might be a double agent and what the ultimate fate of Sarah and her colleagues will be. The interrelations are complicated, set against a diverse and current backdrop of financial issues in the NHS and an ever present terrorist threat.A Most Careless Death twists and turns and the reader is never quite sure where they are being led. Tense and drama filled, it is refreshing to read a tale where the central characters are by and large of pensionable age. This does not however slow the plot which has pace and intrigue to ensure the reader will maintain their interest until the very last page is turned.
