Emil von Qvanten
Qvanten went into exile in Stockholm, Sweden, whence he produced anonymous political propaganda which was smuggled into Finland. In 1855, Oskar Tammelander, working for the Russian secret police went to Stockholm and met Qvanten, but aroused Qvantend's suspicions. So Qvanten supplied the infiltrator with a letter full of literary parodies to excite the suspicions of his contacts in Finland. This succeeded and Tammelander was unmasked as a spy.
