The Untouchables (1959)

S4E14 The Speculator

In 1929, Eliot Ness receives another anonymous call alerting him to a significant gathering at a warehouse on Grover Street, where Nitti and his crew are expected. Upon arriving at the warehouse, he discovers around twenty mobsters busy packing their ledgers into a large trunk. Following Al Capone's downfall due to his financial records, the order has been issued: no one will maintain written accounts anymore. Instead, all records will be centralized, with Leo Stazak appointed as the sole bookkeeper.
