Nick Storie; Deadly Operation

Serena, who Nick met in Morality Play, calls to say there are deaths in the hospital where she is head IC nurse. They are suspicious. The one she called about just happened.
Nick goes to investigate. The chart that had been changed to cause anaphylactic shock that killed the woman has been substituted.
Nick investigates a number of deaths from such causes to find there is a doctor there who is involved in offshore investments. The only connection among the victims is investment in that company.
Then some of the gangsters Nick has met in the past become involved.
