A fine review today in the Providence Journal for The House of Secrets:

Brad Meltzer does what he does best to perfection in “The House of Secrets,” in which he introduces a new hero in Hazel Nash and a new co-author in Tod Goldberg.
That pairing does nothing to detract from Meltzer’s penchant for inventing, and then solving, historical mysteries. In this case, that mystery involves Benedict Arnold being somehow connected to a story Hazel’s father has been telling her since she was a little girl.
