This is document 5 in Lisa Lutz’s Spellman series, and it was wonderful. For those of you haven’t been introduced to the wonderfully dysfunctional family of private investigators, the Spellmans, I recommend starting with document 1, The Spellman Files. It’s not necessary, because the book contains an appendix reviewing all the major players, but it helps. Lutz introduces a few new characters in this book (an ex-con, Demetrius, their grandmother, Henry’s mom) and brings back some of our favorite old players (Bernie, Fred).
These books are just funny. Laugh out loud funny. There’s an appropriate level of romance, with Isabel’s on again/of again relationship with the (probable) love of her life, Henry the cop. There’s quirk, but not reaching New Girl levels of quirkiness. The family is goofy, the things they do to each other in a never ending series of revenge stunts are ludicrous, and there’s usually some kind of mystery tossed in for good measure.
