Ann Granger Victorian novels

Been reading a few of Ann Granger's recent novels which are set in the Victorian ago. There are occasional times when I think the historical attitudes are not quite right but overall I enjoy them. The series starts with Elizabeth Martin, a doctors daughter, taking a post as companion to a distant relative, the rich Mrs Parry. Elizabeth gets involved in investigating a murder and meets Ben Ross, a police inspector. She gets involved in other mysteries in Victorian London, and then marries Ben and they set up in a small house with just one maid, Bessie. Lizzie often helps her husband with investigations, she can talk to people at different levels of society and it is easier for her to win the confidence of other women. THe latest book is about a fence called Jacobus, who is killed brutally in his house which he rarely leaves. Ben uses him as an informant and can never prove that he receives stolen goods. At the same time he is involved in investigating a jewel theft - the stealing of a valuable necklace from a well to do family. It is the London Season and there are many such thefts when the upper classes are wearing their jewels. It turns out that the death of Jacobus is connected to the disappearancee of the necklace. Its a good read
