Critical Mass

Plot

Jocelyn "Joss" Cole, a burned-out public defender from L.A., has opted for a quieter life in the San Juan Islands of Washington state. Joss has no significant clients other than a group of commercial fishermen suffering from a strange and serious illness, a condition doctors cannot diagnose, which Joss believes has an industrial cause. Then into her office comes Dean Belden, a well-heeled client in search of a lawyer to help him set up a business in the islands. Within days Belden is subpoenaed to appear before a federal grand jury. Before he can testify, and before Joss can discover what happened in the secrecy of the grand jury room, Belden dies in the fiery explosion of his floatplane on Seattle's Lake Union.
