In this one an illusionist baffles Rhyme and Sachs (but not for long) by committing gruesome murders. A good plot, well paced on the whole, better than The Empty Chair I'd have to say. The magician theme was interesting since Carol O'Connell has done it too, also set in NY, in her series on Mallory the beautiful foundling cop. A series I kind of like, and then don't.
Not a book to waffle on about though.
