The Deeds of the Disturber: 07/28/13
The Deeds of the Disturber by Elizabeth Peters is the fifth book in the Amelia Peabody series. It's one of two books that doesn't take place in Egypt (the other being the last in the series, which takes place in Palestine).
It's the off season and while the Emersons are home in England. Amelia is tricked into caring for her niece and nephew. Ramses, their precocious son, is in for months of hell.
Although this should be their quiet time, the Emersons are pulled into a murder mystery involving a body left in an ornate Egyptian coffin. There is also an opium den and a man dressing as an Egyptian priest to cast doubt on the nature of the murder.
As it happened, I was listening to this audio (read by Barbara Rosenblat) as I was also reading The Case of the Peculiar Pink Fan by Nancy Springer. Both share similarities in the threat of forced marriage and far away problems surfacing in violence in London. I suspect that both are nods in their own way to Arthur Conan Doyle's A Study in Scarlet.
