The Sherlock Holmes Connection

What is the connection between a murder in 1919 Stockholm and a drug ring in present-day India?
Sherlock Holmes is dead, but his legacy lives on in unexpected ways.
In stories spanning almost a century, in cities half a world away from each other, the magnifying glass of Sherlock Holmes appears just when there is a mystery to solve. But its appearance throws up other questions: who was John Watson? Was he really what he seemed to be? And how and why are his heirs involved in the mysteries?
Two Swedish and two Indian authors–Martin Widmark, Anushka Ravishankar, Katarina Genar and Bikram Ghosh–follow the journey of the magnifying glass of Sherlock Holmes in four gripping mystery stories.
