When Alexandra Richards approaches professional declutterer Ellen Curtis to ask her to help sort out her mother's chaotic flat, Ellen gets the impression Alexandra doesn't like her mother very much. But when Ingrid Richards' body is discovered in her burned-out home, Alexandra's exasperated words don't seem such a joke. Due to the hazardous state of the victim's over-cluttered residence, the police are inclined to dismiss her death as an unfortunate accident. Ellen's not so sure. Could Alexandra's resentment towards her mother have escalated into violence? The more she discovers about the dead woman's remarkable past, the more convinced Ellen becomes that there's something decidedly suspicious about her death.
