A new Curate had been appointed to the Parish of St Guy’s, but somebody didn’t want him there—and trashed the Parish Hall to get the message across. That might not have interested the Hon Richard Rollison—but murder certainly did and it seemed the two were linked. The denizens of the East End docks, West End nightclubs, black marketeers and a beautiful woman all jostle with The Toff as he weaves his way through London’s highs and lows, his path impeded all the way by the Curate himself. If ever a man were his own worst enemy, it would be the belligerent Rev. Ronald Kemp.

Then, one day, Draycott didn't turn up and enquiries lead Fay to the conclusion he had completely disappeared.

So where does he now go to seek a solution to the mystery and can he stay out of danger himself?

A man with a prison lisp was overheard during lunch in the Savoy Hotel in London. He stated that The Toff (The Honourable Richard Rollison) was amongst those he would like to murder. No description is passed to The Toff, but he wonders if it was Charmion, who was released from Dartmoor prison two weeks before - a man who had vowed to carry out such a threat. However, there were many others who might seek revenge. It is a case of too many killers who might 'spoil the murder', but if The Toff is the next victim ...?

The Reverend Ronald Kemp went to the East End of London with definite ideas of right and wrong, in keeping with a minister of the Church. However, the people of the East End had a few ideas of their own, and the Reverend quickly found his world torn apart as he met murderers, prize fighters, and the Toff!

The fog was thick, yellow, sulphurous and impenetrable and just like old times before clean air legislation. Beneath it the villains went about their work quietly and largely undisturbed. Commander George Gideon of Scotland Yard was aware of this and meant to disturb their peace, but before long he found himself involved in a web that was more impenetrable than the fog itself.

Commander George Gideon of Scotland Yard attended the Fiftieth Criminal Investigation Ball, along with his wife, Kate, and daughter, Penny. It was a formal and elegant occasion and a good time was had by all – but Gideon was aware of many undercurrents present in the room. Meanwhile, there were crimes to be dealt with. Instantly, there was a murder, for which a bicycle with a loose-fitting mudguard likely held a clue. Moreover, a collapsed building had trapped many, and a man serving a sentence in Dartmoor prison, for a crime he had not committed, was about to have an unauthorised visitor. Gideon was also concerned for his officers too, which just added to what sometimes seemed like an overwhelming burden.
