Lin Tan goes out to buy some film magazines, finds some clubs looking for new members (rather larger than the small groups she’s interested in, but it’s a start) and writes to them. She rents a PO box, and doesn’t use her own name.

Bessie lurks outside Wigson’s flat, to keep an eye on any non-police presence; there’s nobody obvious, though the Inspector comes out with four constables carrying metal boxes out to a car, presumably full of the film paraphernalia from the flat.

Milly looks through her files for small private investigation agencies that she might have dealt with in one of her other careers, in the hope of finding one that the owner might be willing to sell (and/or give some training). She goes on to check company registrations; neither of the importing companies has any owners she’s heard of.

Gertrude goes to visit Mrs Smith, but doesn’t track her down.

Audrey goes to visit the two film distributors in Soho. There’s no sign of any damage at Kay Film Labs, and she talks to the receptionist, who’s polite, and explains how the import and distribution and translation business works, but off-putting; she gets the impression they’re not really interested in retail business. At Amalgamated Film Importers it’s a little more down-market, and they seem more ready to undertake work for individuals.
