The Daffodil Affair

Appleby is called north to Harrogate on an unusual case. A cab horse named Daffodil has been spirited away from his stables. It seems an otherwise valueless animal except for its trait to be able to discern numbers like a human. At the same time in London, equally intriguingly reports arrive of an reputedly haunted eighteenth century townhouse disappearing from Bloomsbury. At first taken to be the work of German bombers during the Blitz, it has in fact been carefully dismantled and shipped away. To cap it all, two young woman believed to have unusual powers have also been spirited away by a gang.

Before long Appleby is on a cargo ship heading for South America with his colleague Hudspith who believes they are on the trail of a gang of white slavers. Assuming a cover identity they manage to fall in with the leader of the organisation, who invites them to accompany him to his headquarters. This turns out to be located on a series of islands located high up the River Amazon. He reveals himself as a man who is trying to conduct a vast series of experiments in the supernatural in order to try and corner the market in witchcraft and other unnatural phenomena. With the coming destruction of the globe in the ongoing world war, he foresees even more success for his project. He has lured away or stolen a variety of people of objects he believes will help him complete this mission.

Before long it becomes clear to Appleby that he has seen right through their cover story. He is in fact keeping them there in order to kill one of them in the Bloomsbury mansion - rebuilt in the tropics - to see whether the other can sense or see it telepathically. In this Appleby sees a chance for them to turn the tables on their host and escape.
