Your favourite Pitkirtly mystery?

Recently one of the earlier novels in the Pitkirtly series received an excellent review here: http://ignitebooks.blogspot.co.uk/2016/10/cecilia-peartree.html (many thanks to the reviewer! – you may enjoy some of her other reviews too). This reminded me that the novel in question was one of my personal favourites of the series. I won’t reveal what my ‘top 3’ are at the moment but I thought I would use the opportunity to ask any readers who come across this which ones they like best. So if I can get the poll option thingy to work, here we go. I think I’ve set it to accept 3 answers, but who knows what may happen? Feel free to let me know if it does anything unexpected.
