The House in Poplar Wood — K.E. Ormsbee

For as long as the Vickery twins can remember, Lee and his mother have served Memory, while Felix and his father assist Death. This is the Agreement. But one Halloween, Gretchen Whipple smashes her way into their lives. Her bargain is simple: If the twins help her solve the murder of local girl Essie Hasting, she'll help them break the Agreement. The more the three investigate, however, the more they realize that something's gone terribly wrong in their town. Death is on the loose, and if history repeats itself, Essie's might not be the last murder in Poplar Wood. Simultaneously heartwarming and delightfully spooky, THE HOUSE IN POPLAR WOOD is a story about a boy's desire to be free, a girl's desire to make a difference, and a family's desire to be together again.
