Bletchley Circle

Uncustomed Goods, Part 2

Millie's import/export sideline leads to her abduction by a crime ring involved in trading perfume, cigarettes and stockings - and in human trafficking. After her release, Millie is determined to help those sold into prostitution. Millie, Jean, Lucy and Alice decide to tip off Customs and Excise to intercept a contraband shipment and catch the traffickers. The women realize there's corruption in the vice squad and decide to intercept the crime ring themselves, with Jean posing as a potential client. Lucy manages to memorize Marta's ledger, but it's written in machine code. Returning to Bletchley Park, they locate an old Enigma machine, break the code and tip off Customs and Excise. But Marta is on to them.
