"Here's the latest spellbinding thriller from Alistair Maclean - about an enormous, sophisticated, moble oil rig called the Seawitch, anchored off the American coast in the Gulf.. It is owned by a billionaire named Lord Worth - a maverick oil tycoon who's out to beat the big companies at their own game. Technologically very advanced, the Seawitch can supply him with enought cheap oil to undercut prices on the world market -- and there's nothing his rivals can do about it. At least, nothing he can forsee... What he doesn't suspect is all-ut war -- direct armed assaults and a deadly campaign of sabotage, carried out by a ruthless soldier of fortune determined to succeed at any cost. Only two men in the world -- two smart and very competent private eyes -- stand between Lord Wroth and total destruction."
