Dearly beloved, we are gathered here today to talk about the 1938 impossible crime novel Invisible Weapons by John Rhode, one of the many noms de plume of Cecil John Charles Street. We — and by “we” I mean myself and Aidan, who blogs at a frankly prodigious rate over at Mysteries Ahoy! — shall be doing this with many and much spoilers, and from this point on will give away, like, everything.
The reader is warned…

“Aaah! Spoilers!”
