The seven dials mystery by Agatha Christie

This compilation of excerpts details a complex mystery involving a secret society known as "Seven Dials" and a series of suspicious deaths. The narrative begins with a prank gone wrong when a group of friends, including Jimmy Thesiger and Ronny Devereux, attempt to rouse Gerry Wade with multiple alarm clocks, only for Wade to be found dead from an overdose. As Jimmy and Lady Eileen "Bundle" Brent investigate, further deaths occur, including Ronny's, leading them to suspect a larger conspiracy tied to the "Seven Dials" organization, an anti-Bolshevist group operating under the guise of a social club. The story unfolds with secret meetings, stolen formulas, and a revealed identity of the mysterious leader, No. 7, who turns out to be Superintendent Battle, working undercover to expose a dangerous international criminal ring. Ultimately, loyalty and deception are unmasked as the protagonists navigate espionage and murder, with Bundle and Bill Eversleigh discovering they are to be married amidst the chaos.
