By stealth - Colin Forbes

Paula braced herself for the worst . . .

Europe is menaced by an enemy greater than Stalin or Hitler. Paula has her first inkling of danger when a boat vanishes forever in a fog off Lymington. Its sole occupant drifts ashore. Dead. Tweed becomes suspicious when he visits three 'old China hands' living next door to each other in the New Forest. The daughter of one man, an expert in global power, has been kidnapped - with no ransom demanded.

What part is played by the two 'housekeepers' - glamorous Lee Holmes and attractive Helen Claybourne? Who is Vulcan, British controller of a lethal fifth column? Who is sinister Dr Ward - secretive figure posing as a philanthropist? Who is the mysterious murderess, Anne-Marie?

Ships are disappearing in the Far East, off Cape Town, off the German and Danish coasts. Unbeknown to Tweed, two 'invisible' ships - which radar cannot locate - are sailing on a deadly mission ever closer to Denmark. Can Tweed detect the masterplan in time?

Tweed, Paula Grey and Newman - in the most prophetic thriller to date from Colin Forbes.
