The fourth in this authors series of Sherlock Holmes novels, but - while I recommend it - not quite her best, as it lacks some of the page-turning pace and humour of my favourite "Unquiet Spirits". However this could be partly because I put this book down for weeks over Christmas. 

MacBird's Sherlock Holmes are by far the best post-Doyle Holmes I have read, and this one is no exception - it's full of interesting characters and beguiling mysteries, and some artfully touching and insightful moments into Dr John Watson and Sherlock Holmes themselves. 

I'll take an average Macbird over the best efforts of any other Holmes author!
