In Stephen King’s novel The Drawing of the Three, Odetta Holmes’s alternate personality is called Detta Walker.
Odetta is a wealthy Black woman from New York who uses a wheelchair after being injured in an earlier incident. The trauma and psychological division in her history are represented by Detta Walker, a hostile and intensely defensive personality who emerges under pressure. Roland encounters both identities through the doorway mechanism.
Odetta and Detta are later brought into a more integrated identity through Roland’s quest. The combined character is known as Susannah Dean, a name that becomes important in later Dark Tower books. Because Susannah is the eventual shared identity, readers sometimes give it as the answer to questions about Odetta’s alternate personality; the specific name requested here is Detta Walker.
The Drawing of the Three was published in 1987 and expands the series beyond Mid-World by connecting Roland’s world to several periods of New York history.
