When the decomposing body of a young woman is discovered in her bath, initial enquiries at her workplace uncover very little. Reid does not warm to her estate agent boss, while Fraser discovers that she was gifting a significant amount of her less-than-generous salary to charity, but why would that make her a murder target? Meanwhile, Ross learns that his estranged wife is planning to emigrate to Canada with his son, and realises he has a tough choice to make between his family and the job he loves.
