tl;dr
Although billed tongue-in-cheek as "the holiday episode," still retains the same tight plotting and fun meta commentary of the rest of the series.

Thoughts
Even though this is a Christmas book, you should probably grab it before December if you want to read it "as intended." In theory it should be read one chapter a day, like an advent calendar. In practice? Yeah... I finished this a lot quicker. It's a much shorter installment than the prior two books in the series, clocking in at 175 pages. Our self-aware author Ernest explains to the readers that this is because it's a Christmas special, and like every Christmas special, it's should be fast-paced, and easy to skip. That being said, if you're a fan of the series, don't skip this!

Like the rest of the series, it's a tightly-plotted fair play mystery with plenty of drama and some really fun twists. There's also a brand new character introduced who I really hope will be a regular in the series, because he's terrible and hilarious. At this point in time, you know if this series is for you (unless this is your first encounter with Ernest Cunningham, in which case I heartily recommend starting at the beginning). This book features the usual meta commentary, self-effacing humor, and dry macabre sensibilities of the previous books, with the writing now honed even sharper than before.

Thanks to NetGalley and Mariner Books for an advance copy. All thoughts in this review are my own!
