A renegade commander must take matters into his own hands in this epic First World War thriller.

Summer, 1917: Britain is losing the war against the deadly German U-boats. After close fought action, Commander David Cochrane Smith uncovers what he believes is a deadly plot against Britain from a dying German sailor. Code-named Swordbearer, it could turn the tide of the war in Germany's favour.

But, already under suspicion, his warnings fall on deaf ears. With just one one ancient destroyer, a turtle-back 'thirty-knotter' known as Bloody Mary, under his command and a hostile commanding office, he must wage this battle on his own. Smith must solve the riddle and stake his own life to save his country...

This vivid and high-octane thriller is perfect for fans of Douglas Reeman, Alexander Kent and Patrick O'Brien.
