# Sibella Greene — The Greene Murder Case character guide > Sibella Greene in The Greene Murder Case by S. S. Van Dine. **Role:** major **Also known as:** Sibella, Miss Sibella, Sib **First appearance:** 0004-i-a-double-tragedy ## Snapshot A beautiful, brazen Greene daughter whose open contempt for her siblings and hunger for the family fortune make her the household's most dangerous voice. ## Who they are Sibella accuses her sister Ada of shooting Julia with a vehemence that unsettles even Vance, revealing a family in which love has curdled into calculation. Her tirade collapses the moment Vance points out that Ada was herself shot in the back, exposing the illogic beneath her certainty.
