"A MYSTERIOUS 's', WHITE ROSES AND A GRAVE

"A highly confidential assignment took Detective Inspector Rudd to the country village of Barnston. Posing as a civil servant on holiday, Rudd was to secretly protect retired British spy Alec Mercer from an unknown assassin. A blurry World War II snapshot enclosed with a threatening note suggested that the would-be killer's motive was revenge. But for what? Rudd knew it concerned a Resistance fighter called 'S', a bouquet of white roses, and something that happened in France during the winter of '43. But he didn't know who would appear as the Angel of Death in this quiet Suffolk town -- a man, a woman, a stranger ... or a shockingly familiar face."

Excellent plot, combined with a glimpse into English village life in the '50s ... what's not to like? And who could have seen that ending coming? ( )
