Steve Conrad’s dark comedy is full of twists and sad laughs. As for the fate of Harbour’s character, does Lily Allen have an alibi?

Last October, Lily Allen released a jaw-dropping album about the sexual politics of her marriage to actor David Harbour. It was a musical assassination – reportedly written in the wake of her personal sleuthing into his long-term infidelities via the dating app Raya. Therefore the timing of DTF St Louis (Monday 2 March, 9pm, Sky Atlantic), in which Harbour plays a man in a stagnant marriage who downloads a hook-up app to enjoy some extramarital boom boom, is juicy. For everyone except his publicist.

From the trailer, this was a hard-to-read show. Was it a dark comedy, a bedroom farce, a police procedural? The answer turns out to be yes, to all of those things. I also wondered whether it might be a televisual return to the erotic thrillers of the 90s. The answer to that one is no, although it’s a show with sex on the brain.
