[1] In the story, Tuppy Glossop becomes romantically involved with an opera singer named Cora Bellinger.

To accomplish this, Jeeves devises a plan that involves the song "Sonny Boy".

Bertie is singing "Sonny Boy" in the bath when Jeeves tells him that Tuppy Glossop has come to see him.

Bertie slips on some towels, and greets Tuppy, who says he is practically engaged to an opera singer, Cora Bellinger.

She dislikes practical jokes, and heard about the time Tuppy tricked Bertie into falling into the Drones Club swimming pool.

Tuppy tells Bertie that their friend "Beefy" Bingham, a parson, runs a clean recreational establishment in the East End.

To impress her, Tuppy will also be there to soulfully sing "Sonny Boy"; this shocks Bertie, who holds strong views on the song.

Aunt Dahlia arrives and says that her daughter Angela has had her heart broken by Tuppy, who left her for Cora.

He believes Cora will lose interest in Tuppy if he is unpopular with Beefy's audience.

Jeeves suggests that Bertie sing "Sonny Boy" first, so that the audience will be tired of the song by the time Tuppy performs.

Then Beefy takes the stage, and says that the next performer, Cora, will be late because her car broke down.

Bertie clutches at Jeeves, shocked that Cora was not there to see Tuppy's failure.
