What have Stonehenge, puppets, King Charles I, and characters from an Alexander Dumas story got in common? The answer is contained within the carefully crafted Sherlock Holmes on the Western Front. The plot, as is usually the case with anything written by Val Andrews, is imaginative and involves the world of entertainment.
It is 1916 and the allies are losing the Great War. It has been a terrible two years. Mycroft Holmes enlists the assistance of his brother Sherlock, along with an eager Dr. Watson, to investigate how military secrets are being passed to the enemy.
In the guise of concert performers for the troops, Holmes and Watson are sent to Salisbury Plain prior to being sent over to the Western Front. However, very soon they discover just how coded messages are being sent to the Germans. A trap is set and the culprits caught, although the chief spy escapes ... but not for long as Holmes is able to track them down to a safe house where they are arrested.
For the final part of the adventure our heroes travel to France to infiltrate the spy ring. Here they unearth a secret tunnel which may well alter the whole course of the war.
