On a wintry November morning, both the Prime Minister in Downing Street and the US Ambassador in Grosvenor Square receive an appalling ultimatum - a nuclear device, concealed somewhere in London, will be detonated within 72 hours unless the British and United States governments accede unequivocally to teh demand for an independent Palestine.With chilling plausibility, Antony Trew describes how a group of ultra-millitant terrorists - disavowed by Yasir Arafat and the PLO - hijack a nuclear warhead, smuggle it into Londo, issue the ultimatum, and so trigger off a macabre treasure hunt which has the lives of hundreds of thousands of Londoners at Stake.There is a grim reality in the account of Cabinet discussions in Downing Street, of hot-line consultations between heads of state, of desperat efforts by security services and secret agents to trace the warhead - all against a background of suspense and mounting tension as information trickles in and the minutes tick away...

The deck of Ocean Mammoth stretched nearly a fifth of a mile from bridge to bows; its superstructure rose above the water-line to the height of a ten-storey building; loaded it displaced 320,000 tons. It was among the latest and finest of the monster tankers that swarm in ever-increasing numbers across the oceans, yet in a time of falling freight rates and dwindling cargoes it had no useful part to play. It had to die. but the death of a supertanker is not easily contrived if it must appear to have been an accident.The conspiracy to take Ocean Mammoth to her doom involved meticulous planning an ruthless execution. Even then the story was far from over, for who was responsible? The formidable, withdrawn Captain Crutchley, whose secret disability nagged incessantly at his security? Freeman Jarrett, the flamboyantly handsome chief officer driven by relentless ambition and boundless conceit? Foley, the capable but colourless navigation officer, striving to hold a wife too...

It was the custom of the German Naval Command in the Second World War to name Allied convoys after the U-Boat commander who made the first sighting report. Kapitanleutnant Johan Kleber sighted convoy JW137, Murmansk bound, as it battered its way through the freezing storms and gloom of an Arctic winter, and so 'Kleber's Convoy' it became. The U-Boat's signals were intercepted by the Admiralty in London and passed back to the commanders of the British escort vessels; notably to the Lieutenant-Commander Redman of the destroyer Vengeful. The name of the U-Boat commander was for him a painful shock: years before a Hans Kleber had saved his life on a Swiss ski-slope, he had fallen in love with the German's sister and still reproached himself for her accidental death. Could this be the same man? Was the relationship between these two friends and enemies to provide a haunting counterpart to the savage naval battle? Kleber, with fifteen U-Boats concentrating for the attack, was...

For nearly a year Charles Black has been stalking his prey and now, on the lovely island of Ibiza, he is very close to his victim. When the lean white schooner Snowgoose sails into the harbour, Black knows it is time to move in for the kill....

Lieutenant Commander Widmark had truly earned his nickname 'The Butcher' in mediterranean waters. He derided the Geneva Convention and the pusillanimity that sometimes delayed action against the enemy for diplomatic reasons. In his view war was a rough and bloody business in which those who stopped at nothing would be victorious. This is the exciting story of Widmark's greatest adventure, the organization and execution of a private cutting-out operation designed - regardless of any consequences - to strike a single telling blow for his own side. Widmark plans to seize and sail the 8,000-tonne German vessel, Hagenfels, from the neutral East African port of Lourenco Marques. All these events and fantastic developments thereafter, are brought to life by the author's knowledge of sea-going and the power of narrative that brought him worldwide success.
