Murder by the Lake

Curse from the Depths (1x10)

:

Treasure hunter and diver Florian Friedrichs, his girlfriend Stephanie, and assistant Manuel Mohr recover a fabulous hoard of 17th century gold coins from the bottom of Lake Constance. The coins are the legendary 'Pestilence Pennies' which the Bregenz townspeople had paid in 1630 to a local witch in hopes of ending a recurrence of the plague. A few days later, however, Friedrichs is found murdered with a gold coin in his mouth and his lips sewn together. Detectives Zeiler and Oberländer soon find that Friedrichs had made many enemies well before the treasure find. And the treasure was supposed to be cursed by the witch. Could the curse be coming true? Matters are not helped by Oberländer's abrasive behavior towards his colleagues, caused by the events of episode 9.
