The Lamp from the Warlock's Tomb, Anthony Monday #3 by John Bellairs
Miss Eells purchases a suspiciously cheap antique oil lamp and unwittingly sets off yet another doomsday countdown. Well, to be fair, it's not a doomsday countdown, it's just a countdown to giving an unscrupulous woman god-level powers. No biggie.
I still don't like how Anthony Monday and Miss Eells became supernatural detectives, but this book is so spooky and spectacularly gruesome that it charms to this day.
The lamp, of course, was stolen from an elaborate tomb. Once lit, Anthony and Miss Eels begin to be stalked by an entity with a cobwebby face and lives are lost. Add in an appearance from Ashtaroth, winter sports, and the most interesting chamber of commerce mixer ever devised, and you have a swell mystery on your hands.
