I'm listening to The Devil in the Marshalsea by Antonia Hodgson, read by Joseph Kloska. It's set in 1727 when Tom Hawkins is committed to a debtors' prison for non payment of his rent. Life in the Marshalsea could be quite comfortable if the prisoner had access to funds and utterly hellish if not. A view of the seamier side of London life, quite good so far.
I'm reading The Prayer of the Night Shepherd by Phil Rickman (Merrily Watkins #6). The theme this time is Sherlock Holmes and The Hound of the Baskervilles. I'm looking forward to watching Midwinter of the Spirit on the TV later. I think that Anna Maxwell-Martin is a good choice for Merrily and David Threlfall looks how I imagine Huw Owen to be.
Regarding The Long Earth discussion above, I read it fairly recently too and was a bit underwhelmed. I'm a TP fan, so blamed Stephen Baxter. Perhaps it's just that the sum of the two is less than the separate parts. I'm planning to read the next book in the series at some stage.
