This was a wonderful and literary murder that starts with an elderly gentleman interested in the figure of a bird. He ends up dead much the same way as the murder victim in an Agatha Christie novel and would have been ruled death by natural causes if it hadn't been for Jennifer's suspicions. When a life coach is murdered ala Sherlock Holmes it is obvious that Jennifer is on the right track and she becomes a consultant for Frank! Finally, no changes to the cast (except our medical examiner is strangely missing).
Together Frank and Jennifer solve this murder. Great mystery and I learned that Agatha Christie worked as a pharmacist in WWI which is why she uses a lot of poisons in her murder mysteries. This is a strong recommendation to cosy mystery fans.
