The Secret Jungle

With many daring missions during World War II, Kurt Brandt had served his country well. From their hair-raising attacks on British warships before and on D-Day, along with the deadly task of delivering and retrieving spies under the cover of darkness in their powerful, high-speed, torpedo boat.
Their final act of bravery at war’s end involved bringing boatloads of refugees from a battle ravaged Latvia to surrender in Portsmouth, England. Those people were desperately escaping the vengeful retribution of the Red Army, which, surprisingly, led to some of those abused refugees volunteering to train for secret service duties in order to help the West. Their goal was to get the coveted military intelligence by peeking behind that immovable 'Iron Curtain' that usual operatives found virtually impossible.
Called to attend an interview at an anonymous building in London, Brandt was offered the job of putting those brave female agents into the Russian-occupied Baltic States, dearly hoping they could actually get the sorely needed military information back to the Western Intelligence Services.
They named this foray: Operation Jungle. Most of the agents they used were beautiful, Russian-speaking women,prepared to do whatever it took to get those closely guarded soviet secrets.
Brandt accepted the task but had to deal with the complication of three women in his life. One was a beautiful Latvian woman that ran a spy ring for MI6 called Eva Dietrich. The second was a Russian born Ukrainian called Natalya that he’d met by chance on the Danish island of Bornholm. The third and most significant was the powerful and extremely fast S-boat that he captained.
Desperate to hold it together after some tragic and deadly experiences with women in England and Hamburg, things became further complicated because he and Eva became lovers. Unfortunately, during her last mission, she'd been captured and was now held in the notorious Karosta Prison in Latvia awaiting KGB interrogation. Brandt, along with his crew and some British Special Boat Service men, set out to rescue Eva before she could reveal any secrets under torture as it could blow the whole organization wide open.
Unknown to Brandt, the SBS men had orders to kill Eva if her escape was thought impossible, purely to secure the lives of the other female operatives.
Could Brandt and his men get her out before those cruel interrogators from Moscow arrived or were all their fates sealed right from the start?
