Silent in the grave : aLady Julia Grey mystery, book 1

Summary: "These ominous words, slashed from the pages of a book of Psalms, are the last threat that the darling of London society, Sir Edward Grey, receives from his killer. Before he can show them to Nicholas Brisbane, the private inquiry agent he has retained for his protection, Sir Edward collapses and dies at his London home, in the presence of his wife, Julia, and a roomful of dinner guests. Prepared to accept that Edward's death was due to a long-standing physical infirmity, Julia is outraged when Brisbane visits and suggests that Sir Edward has been murdered. It is a reaction she comes to regret when she discovers the damning paper for herself, and realizes the truth"--Book description.
