A few critical notes on Elly Griffith's The Frozen People

This week, I took some time out to read Elly Griffith's most recent book, The Frozen People. I thought this sounded quite an interesting genre-fusing novel, welding together detective fiction and SF/time travel. Sure, it's hardly the first to do so, but it sounded worth a read. I'd met the author a few years' back through a mutual connection: Lesley Thompson, another British crime writer.
