Commander Blake is still dealing with the aftermath of the James Lampton case. Not only has he pleaded not guilty to the murders for which he is accused, it now means that Blake will have to testify about their sexual relationship. With the added news coverage, Blake finds that the sister of one of Lampton's victims is now stalking her. Blake's own sister, who is terminally ill with cancer, moves in with her. In a separate case, a computer hacker who has gained access to online medical records and changing information is terrorizing St. Barnaby's hospital. His first victim is someone who had a severe allergy to nuts and the second is someone who is allergic to penicillin. The hacker threatens to kill one patient every 24 hours if he doesn't receive 20 million pounds.—garykmcd
