Puzzle #157: Monster Mash (by Richard Shlakman)

This week, I'm happy to host an appropriately spooky guest puzzle by Richard Shlakman (pdf, puz, pdf solution). Richard's an esteemed frequent collaborator of mine - you might have solved puzzles by us recently in AVCX and Crucinova. A version of this puzzle was originally accepted at the Chronicle of Higher Education before they canceled their crossword, so it's finding a home here. Richard wanted to add that he's honored to have it featured as a guest puzzle here - and I'm honored to host it!
