If I liked Broken Colours, Tracks and Passenger List.....

[BaconAndAvocado]

....what else might tickle my fancy?

We have similar tastes and I've enjoyed There's something I need to tell you, The Cipher, Tumanbay (all 3 by John Scott Dryden who wrote Passenger List), Restart, Forest 404, Red Moon, The System. Most of the things listed under search > browse all speech > Drama > SciFi , & Thriller on BBC Sounds. Also everything by Julian Simpson in the Pleasant Green universe (Lovecraft Investigations etc).

Agapornis
Thank you!
Are they all bbc?
I listened to Passenger List on Apple Podcasts.

Yes, but they're usually on other platforms too - as they say, 'wherever you get your podcasts'. Had a quick check and all except Red Moon are on Spotify, so I presume on Apple too.

Any of the Limelight series on BBC Sounds:

Bitter Pill
Galapagos
Incident at Ong’s Hat
English Rose
Harland
Exemplar
The System

The Aldrich Kemp ones are tongue in cheek.

Agree that the Limelight series is good. I'd add Siege to the suggestions.

Thanks all.
I'm in the middle of The System.
Loving it.
