Inspector Mallory, required to prove his community involvement to retain his post, joined Roger Frobisher's local bowls club, trusting it's the only one where he can just sleep through everything. Roger's flirtatious visiting brother, Scotland Yard Commander and former Neurenberg Nazi hunter Alec Frobisher, is garroted during a match. To Mallory's horror, the case is taken from his, as technical suspect, and given to Inspector George Ironside, who is confident to get the Kembleford post after cracking the case. New he turns to team-Brown, which can't be barred more then he always failed, and acts as their spy in the police station. Player Eric Worcester is found to be a former SS soldier, who married Auschwithz survivor Christina, but oddly he is murdered shortly after. Brown works out all secret identities, but that proves most dangerous for him and Mallory.
