Margery Allingham: The Mind Readers (UK 2008)

From the Publisher:
Fact catches up with fiction when the secret of telepathic communication is discovered. But the device at the centre of the mystery is in the possession of two schoolboys and whether they stole it or invented it, there are powerful interests who will kill to get hold of it. Albert Campion faces as deadly a challenge as any in his career.

Margery Allingham: The Mind Readers (USA 1972)

From the Publisher:
Two small boys have shattered the thinking world with a Nipponanium Iggy tube. With it they found they could be mind readers. They could "feel" what was thought a hundred miles away. It scares Albert Campion because they take it for granted. But the murder and chicanery it has brought is something else to be reckoned with.
