Particularly for a mystery, one needs a wide enough cast for there to avoid obvious red herrings or red shirts. I love the variety of characters and backgrounds, although this particular edition spends more time with the upper crust. The characterization is interesting, there are developments in Peter's personal life, and the overall arc of the series takes a satisfying and solid step forward. That said, this was quite possibly my favorite installment of Peter Grant's story yet. The more I love a book, the harder it becomes to review, because I don't want to move out of my state of enjoyment to one of analysis. Peter Grant is back, as are Nightingale et al at the Folly and the various river gods, ghosts and spirits who attach themselves to England's last wizard and the Met's reluctant investigator of all things supernatural. And blood, mixed with magic, becomes a job for Peter Grant. The place has a bloody and haunted legacy - and now blood has returned to the empty Mayfair mansions of the world's super-rich. Along Oxford Street, the last trip was taken by the condemned. The 'Hanging Tree' was the old colloquial term for the Tyburn gallows, which stood where Marble Arch now stands.

Every one of the previous novels in Ben Aaronovitch's series about Peter Grant has made the top ten of the Sunday Times' hardback bestsellers' list, and The Hanging Tree looks set to repeat the feat. A tour of what remains and an insight into what once was with a liberal sprinkling of folklore, myth and violent crime. Another gripping and hilarious adventure through the secret streets of London.
