The Secret Diary of the Master was a short story by James Stoker published in Issue 490 of Doctor Who Magazine, shortly after the broadcast of TV: Death in Heaven. It posited that, throughout their lives, the Master kept a diary, which was found by UNIT after Missy's apparent death at the graveyard in the aforementioned television story.
A UNIT clean-up team, headed by Malcolm Taylor, find a black book at the site of the recent incident involving the Doctor and Missy. It is in fact the Master's diary. Enthusiastically noting that it may fill some gaps in UNIT's file on the Master, Malcolm emails it to Kate Stewart and the rest of UNIT Command in both Geneva and New York, recommending that it be placed in the Black Archive. He also attaches twenty-seven extracts from the diary, ranging from the Master's first attempt to invade Earth to Missy's latest. Chillingly, the last entry appears to have been written after Missy's Cyberman scheme failed, suggesting she survived her apparent execution by Alistair Gordon Lethbridge-Stewart.
