Cold Smoked by K. K. Beck

Under the terms of eccentric Uncle Harold’s will, Jane da Silva can only access her trust fund if she investigates “hopeless cases” for the Bureau for Righting Wrongs. Low on cash and waiting for a hopeless case, Jane is singing the blues in a Seattle hotel lounge during a seafood convention. When a young woman is shot to death, Jane agrees to help the woman’s family find the murderer.
