Sinister tide - Colin Forbes

The wave of the future confronts Tweed - carrying death for a hundred million people. With Paula Grey and Bob Newman, Tweed tracks the creator of the supreme weapon, Dr Goslar. Identity unknown - man or woman? 

The trail leads from the coast north of Dartmoor to London. Two mysterious women appear - Serena Cavendish, then Trudy Warner, just arrived from the US. Can Tweed trust either? Captain Alan Burgoyne, Gulf War veteran, joins Tweed's team. The Yellow Man surfaces - the most savage assassin Tweed has ever encountered.

The pursuit of Goslar moves to Paris. Tweed has many enemies - the French security services, a 'non-existent' American unit, the rival British Special Branch, all determined to seize the weapon. From Paris, Tweed, always under threat, races to Geneva, on to Annecy.

Goslar's base is still unknown. He is close to delivering the weapon to the West's most fanatical opponent. is Tweed too late? A crescendo climax explodes in remote snowbound mountains.
