Murder at Hartigan House by Lee Strauss
Murder at Hartigan House picks up where Murder on the S.S. Rosa left off. Ginger has just arrived back at Hartigan House in London where she grew up, to take care of her deceased father's estate and decide what she wants to do with the house. The house has been shut up for the past 10 years and has just been readied for her return. There is some distressing news, however. Pippins, the family's long-time butler, has discovered the body of a woman. When circumstances and evidence begin to point towards her father, Ginger decides to investigate and once again finds herself "assisting" Chief Inspector Basil Reed.
