The Halloween Haunting

It's bingo night at the retirement center! It sounds tame enough to Mallory, except the residents of this particular community include a grandmotherly hacker, a retired witch, and, once upon a time, Mallory's Great-Auntie Lula. Visiting her dead relative's former abode brings back memories for Mallory, but it also rather unexpectedly brings back Great-Auntie Lula. With her ghostly great-aunt's help, can Mallory and her crew discover who's burgled Bradley's condo, and why everyone involved with the break-in keeps dying?
