Cosy Moments, left under sub‑editor Billy Windsor, is seized by Psmith (with Mike) and reinvented as a muck‑raking weekly exposing tenement abuses.
The exposés provoke violent pushback from gangs and the corrupt owner Stewart Waring, prompting street brawls, the recruitment of pugilist Kid Brady and the enlistment of Groome Street boss Bat Jarvis.
By skilful investigation (notably a rent‑collector's receipt) and tactical pressure they compel remediation, revive the paper's fortunes, and conclude with the reform vindicated despite Windsor's brief imprisonment.
Mike Jackson, a talented young cricketer, is bowled when John Bickersdyke walks behind the bowler’s arm; family losses force him into the New Asiatic Bank, where he meets the eccentric Psmith.
Psmith befriends and manipulates office life (winning over Rossiter, haunting Bickersdyke) and shields Mike through a cheque incident, while Mike grows restive in banking.
When called to play for the county Mike scores a century at Lord’s; Psmith decides to leave for the Bar with his father’s backing and offers Mike patronage, and both quit the bank.
