It's June AD80 and four young Romans are spending a holiday in the Bay of Naples. Murder is committed nearby and a poisoner is at large among the guests at the villa. With their talent for solving crimes, the foursome decide to try to catch the culprit. Caroline Lawrence has a wonderful talent for bringing the past alive to young readers. This is eleventh in the Roman Mysteries series and is just as good as the earlier books.It is interesting to see how the characters are developing and growing older. The mix of girls, boys, wealthy and former slaves works well giving glimpses of very different lifestyles. The storyline is gripping and keeps the attention throughout. Definitely worth reading.
