The issue of women's rights pervades Inspector Thomas Pitt's tenth adventure in late 19th-century London. Three Members of Parliament have had their throats slit while crossing the Westminster Bridge. All three voted against female suffrage. As Pitt investigates, his suspicions fall on a vocal and much-wronged suffragette; other unlikely candidates include anarchists and madmen. As usual, Pitt's wife, Charlotte, and her delightful Great Aunt Vespasia play sleuths as well. Perry uses well-mannered prose, satiric wit, and fine sense of place and time to construct a completely believable and human world. A sterling performance and a collection must.
