Strange grid today, with a totally unchecked word. The theme is, I guess, pyramids, or ancient Egypt, and thematic fill includes PYRAMIDSCHEME (17A: Common scam), TOMBRAIDER (21D: Video game featuring an archaeologist heroine), PHARAOHANT (23D: Insect with multi-queen colonies), TUT (28A: King of the 18th dynasty), the afore-referred-to, unchecked MUMMY, and, possibly, LOOTERS, LAWBREAKERS, CAGEDUP, and ALIENS (45A: Builders of the pyramids). Just kidding about that last clue, but I've gotta believe they were thinking about that.
On the other hand, I don't really like "22A: Leave in a bad way" for STRAP. Are they talking about whipping someone with a strap? Yikes.
My error came at the ABBA (33A: Bishop's title in the Coptic Church) and OPERASERIA (4D: Work not of the buffa style) cross. I went with the French ABBe, and "Opera Serie" seemed like plausible French as well, but "buffa," I see, should have indicated Italian. Oh well... tough cross.
1A: Mitch who wrote the best seller "The Five People You Meet in Heaven" (ALBOM) gets a C-. Don't read, don't believe in Heaven. My first confident answer was PEEPER (11A: Tree frog with a distinctive call).
So meh from me. The unchecked word was rather bluntly clued, and I guess the puzzles hidden charms remained sealed off from me.
p.s. I chose the photo of Harold Ramis that I thought looked most like Colum. :)
