I watch Lady in the Lake every Christmas season.I've yet to see any of those Hildegarde Withers mysteries...need to pick up that Warner Archive set at some point.
Nice write-up on Boston Blackie, Marv! I'd love to see some of these in better shape than the few available on YouTube. Sad that none of the Chester Morris entries ever made it on to pressed DVD (there are a few fairly expensive MOD titles from Sony). I have listened to many Boston Blackie radio shows back in the day, and enjoyed those quite a bit.
It's not part of a series, per se, but the 1946 Philip Marlowe flick Lady in the Lake (directed by and starring Robert Montgomery) is set at Christmas and has some fun Christmas cheer interspersed with all the violence, double-crosses and sleaze. It's got that odd gimmick of being filmed from Marlowe's point-of-view, but it's a pretty good noir and features a really good role for the sultry Audrey Totter.
