All-Consuming Fire — or, more completely, All-Consuming Fire: Being a Reprint From the Reminiscences of Doctor John Watson — was a Sherlock Holmes book by Arthur Conan Doyle. The Seventh Doctor once gave a copy as a gift to Benny and Ace. Benny read it in March 1843 in Jabalhabad, India. Ace, for her part, said she'd "wait till the film [came] out".
The story was the account of an adventure that Holmes and John Watson — names Conan Doyle gave to two non-fictional people — had with the Seventh Doctor, Ace and Benny.
Benny claimed that Conan Doyle had characterised Ace perfectly, but that he wasn't so spot-on with Benny herself. She was noncommittal as to whether the author had done the Doctor justice. Benny also said that she didn't "remember half of these things happening" — implying that the author had taken some literary licence with the facts. (PROSE: All-Consuming Fire)
