“Mimicking of Known Successes” by Malka Older is the queer second-chance romance f2f anti-capitalist cozy science fiction  Holmesian mystery that you didn’t know you wanted.  A man goes missing from the colony of Jupiter, and investigator Mossa is assigned the case.  She engages Pleiti, a researcher into Old Earth (and her former lover), to help her investigation.   They are immediately immersed in university politics and backstabbing colleagues.  Mysterious Hijinks Ensue!  Tea is drunk and scones are eaten!  Everything is questioned.  It is a romp with wonderful delicious layers.  Highly recommended.
