A review by ederwin
The Brotherhood of the Seven Kings by L.T. Meade, Robert Eustace

3.0

I actually only read one chapter of this, "THE LUCK OF PITSEY HALL", but it is an interesting discovery. It is similar to Sherlock Holmes, but instead of Professor Moriarty, the evil scientist in this is a woman.

The whole thing is available on Wikisource and there is also a Librivox version. Dated, but entertaining.
