Adolf Verlof runs a sex shop in 1880’s London, but his real profession is even shadier. He’s a so-called "agent provocateur" for the Embassy, whose mission it is to infiltrate and spy on a relatively harmless group of anarchists. His employers are impatiently waiting for the group to do something radical enough that they can use it as an excuse to harden their actions against the many socialist and anarchistic groups that are sprouting up around the country.
