The title comes from a quote by Captain Ahab in Herman Melville's seafaring classic 'Moby Dick': "Towards thee I roll, thou all-destroying but unconquering whale; to the last I grapple with thee; from hell's heart I stab at thee; for hate's sake I spit my last breath at thee."
Loosely based on an old Sherlock Holmes mystery, The Problem of Thor Bridge.
Though Len Cariou originated the role on Broadway, George Hearn starred opposite Angela Lansbury in the national tour of Sweeney Todd: The Demon Barber of Fleet Street (1982).
