I love the historical crime novels of Steven Saylor. Gordianus the Finder is a wonderfully wraught character, Saylor spins expert webs of mystery in his stories and the history of the pieces is nothing short of excellent. As far as I can tell. They're wonderfully snug vibrant, lusty, curious, alive novels and I always look forward to a new one appearing. The Seven Wonders is a prequel to the other novels; it takes place when Gordianus is a mere 18 years old and travels around the Seven Wonders of the Ancient World with his tutor Antipater of Sidon. As we get to know the wonders as they stood at that time Gordianus also solves a new mystery at each one. But perhaps there's a great one tying them all together....? Read this, it's so enjoyable and you (at least I) learn a lot along the way. The best kind of historical crime novel.
