A more than professional interest . . . a more than personal intrigue.

Orlando Coppersmith should be happy. WWI is almost a year in the past, he’s back at St. Bride’s College in Cambridge, his lover and best friend Jonty Stewart is at his side again, and—to top it all—he’s about to be made Forster Professor of Applied Mathematics. And although he and Jonty have precious little time for an investigative commission, they can’t resist a suspected murder case that must be solved in a month so a clergyman can claim his rightful inheritance.

But the courses of scholarship, true love, and amateur detecting never did run smooth. Orlando’s inaugural lecture proves almost impossible to write. A plagiarism case he’s adjudicating on turns nasty with a threat of blackmail against him and Jonty. And the murder investigation turns up too many leads and too little hard evidence.

Orlando and Jonty may be facing their first failure as amateur detectives, and the ruin of their professional and private reputations. Brains, brawn, the pleasures of the double bed—they’ll need them all to lay their problems to rest.
