The last thing recently widowed Julia Probyn expects to find on the lush and charming island of Madeira is a clue to her husband's mysterious death, for Colonel Jamieson perished somewhere in the wilds of Central Asia while on a top-secret mission for British Intelligence. No sooner does Julia arrive at Madeira with her infant son and his devoted Nanny, however, than a series of strange, sinister, but apparently unconnected events begin to occur. Suspecting a Cold War plot, Julia summons her cousin, Colin Munro, and together they might just be able to blow the entire Russian scheme wide open.
