In the last few months, there have been eleven burglaries at Bel Gardens, an upscale apartment complex, the latest the first where there has been a fatality, the victim Albert Duval, the resident being robbed. Mike figures that the burglars are either led or assisted by someone on the inside, namely a tenant. Duke is not enthralled with Mike's plan if only because of the cost: that he and Nikki go undercover as new residents, husband and wife Edgar and Edna Elliott, they who are to be as ostentatious as possible to be too big a lure for that tenant. A twelfth burglary occurs during the welcome party Mike and Nikki hold for all the tenants of the building, which does not rule out the involvement of anyone who attended the party, or even any of the victims. The party confuses the matter if only because Mike senses that all the tenants individually are hiding something in order to maintain the façade of wealth. Mike figures that another party, that given by Albert's widow, Lydia Duval, will give the burglars ample opportunity to rob their place, which will be watched. The danger for Mike and Nikki is their cover being blown in their continuing association on the case with Duke and Homicide Detective, Lieutenant Hank Broidy, especially if one of Mike's theories on how the inside person may be getting his/her information is correct. Meanwhile, Duke doesn't like the fact that Mike has been practicing shooting at the shooting range.
