With Matty's help he tracks down a warehouse which has links to one of the deceased and almost dies in the warehouse when the villains set it alight. Holmes escapes the building, and determines that he must travel to Guildford and locate an expert in exotic diseases who might help identify the yellow substance. He, therefore, sets out with Matty on his barge to Guildford, and although they are attacked along the way by the villains, they nevertheless make it to his destination and discovers that the yellow substance is bee pollen. On returning home he visits his tutor's home, where he meets Crowe's daughter Virginia.
A few days later Sherlock is lured to a fair, where he is forced to participate in a boxing match, from which he is kidnapped and interrogated by the unseen Baron Maupertuis until he is rescued by Matty, and the pair go to his tutor's home. Knowing that the Baron has left his headquarters, Sherlock, Matty, Amyus Crowe and Virginia determine to follow and locate the Baron.
They discover that the Baron is shipping a weapon from a London wharf, and after a series of chases, Sherlock and Virginia are kidnapped to France by the Baron, and further interrogated. The Baron attacks Sherlock as Mr. Surd attacks Virginia. The pair escape and meet up with Crowe and Matty and set out to stop the Baron from trying to destroy the British Army. They find a fort, where Mr. Surd is in. Sherlock engages in a fight with Mr. Surd, and Sherlock kills him by shoving him into a beehive, resulting in multiple stings from angry bees. They throw pollen in the air, and burn it. The fort falls down.
