Safe as Houses

The Major Crime Squad and the Bureau of Criminal Intelligence lock horns over Carlos, an informant. While Forensic endeavour to narrow down possible sites of the lead contaminated soil, the Majors sift through endless threads of information. The Drug Squad lose track of Chris while she is undercover with a drug dealer and the top brass take Murdoch to task about the number of complaints against the Majors. Chris eventually turns up in an unexpected place - outside a 'safe house' that is raided by the Majors. Suddenly there is a cross-over between the Drug Squad and the Majors. Caught in the net is a brand new player John Rhys.
