Cambridge, 1906. On the day Jonty Stewart proposes that he and Orlando Coppersmith move in together, Fate trips them up. Rather, it trips Orlando, sending him down a flight of stairs. Instead of taking the next step in their relationship, they’re back to square one. It’s bad enough that Orlando doesn’t remember they were lovers—he doesn’t remember Jonty at all. Back inside the introverted, sexually innocent shell he inhabited before he met Jonty, Orlando is faced with two puzzles. Not only does he need to recover the lost pieces of his past, he’s also been tasked with solving a four-hundred-year-old murder before the end of term. The college’s reputation is riding on it. Crushed that his lover doesn’t remember him, Jonty puts aside his grief to help decode old documents for clues to the murder. But a greater mystery remains—one involving the human heart. To solve it, Orlando must hear the truth about himself—even if it means he may not fall in love with Jonty the second time around…
