H.M.S. Unseen is the third mystery novel in the Admiral Arnold Morgan series by author Patrick Robinson.
H.M.S. The Unseen is one of the deadliest and most effective submarines ever built. During a training mission off the coast of England, it disappeared, hindering military intelligence on both sides of the Atlantic, including national security adviser Admiral Arnold Morgan. A missing weapon is dangerous enough. The plane started to explode in the sky.

Morgan firmly believes that only one man can be behind all these devastating events. His arch-nemesis, the world’s most cunning terrorist spy – but presumed dead. Determined to stop his old foe, Morgan must use all his wits to find a madman armed with a powerful submarine lurking somewhere in a million square miles of ocean. Little does Morgan know that the fanatical terrorist has a plan of his own, one that will pit these two powerful warriors face-to-face – and only one will survive one of the creepiest spy stories ever of year.
