The Paperback Sleuth - Ashram Assassin

When a set of rare, impossible-to-find yoga books are stolen from a West London ashram, its leaders turn to Cordelia, the paperback sleuth, to recover them - a set-up that's a little awkward as they've previously barred her from yoga classes for selling marijuana to their students. Can Cordelia work out who the killer is and bring them to justice before they bring an end to her sleuthing for good.
