of his family are unknown. There is speculation that Kalinin has betrayed Mithril to Amalgam, due to his meeting with Leonard Testarossa at the end of the book 'Dancing Very Merry Christmas' and also due to his mysterious disappearance and attitude during the raid by Amalgam on Mérida Island. Kalinin later appears in 'Tsudou Make My Day' at Leonard's villa, apparently as one of Leonard's subordinates. He later shoots Leonard in the chest before Leonard could detonate the TARTAROS system along with Mérida Island. In a final knife battle with Sousuke, he is mortally wounded by Sousuke just before the nuclear missile hits the island. Kalinin mentioned that he had difficulty maintaining family ties, mostly with his wife, due to his time spent with the Spetsnaz. He seems to be of a family man sort and loves his wife so much that he made the Borscht (that Sousuke avoids at all costs) that his wife made him as he returns from missions. He operates under the codename Perth 1. Richard Mardukas Richard Mardukas is an overly protective aide of Tessa, who insists on guarding her with his life. He holds the rank of commander and is in charge of Mithril's TDD-1 when the captain, Testarossa, is not on board; appropriate, given that Mardukas' position is that of executive officer. Mardukas is often seen wearing a hat bearing the name of HMS Turbulent, a real British submarine. Before joining Mithril, Mardukas was the commanding officer of HMS Turbulent, and a graduate & instructor of the Royal Navy's "Perisher" course: the submarine equivalent to the US Navy's famed "Top Gun" Fighter Weapons School. According to the FMP novel A Dancing Very Merry Christmas, Mardukas was known to the submarine community as a genius of submarine warfare, leading to his nickname "Duke"; he also served on HMS Conqueror when it sank the General Belgrano, and while commanding the Turbulent saved Tessa's father and his submarine on a secret mission. Many of his peers in the submarine community, such as Commander Killy B. Sailor, CO of the USS Pasadena, believe Mardukas to be working in a shipping firm after his retirement. A running gag throughout the series is that he usually ends up giving sermons to lower officers on deck.
