Note:

• The Wrong Doctors saw the Doctor drop Mel off at the wrong place on Earth shortly after the Trial and his later self (wearing his blue outfit) arriving to early to meet her shortly after Evelyn's departure from the TARDIS.
• Like with the 4th and 5th Doctors, 6th drops his companions off somewhere of their choosing and later pick them up. Peri remained on Earth sometime after the events of The Reaping leading while 6th travels with Frobisher and later rejoins the duo.
• Frobisher, much like later companion Raine Creevy traveled on and off with the Doctor. More sporatically after the events of TOATL and moreso after the sixth regeneration into his 7th incarnation whilst Mel was dropped off elsewhere.
• If you're wondering why Instruments of Darkness is omitted, it's more down to how 6th and Evelyn's relationship was handle there (Evelyn especially). Granted the book was published four years before the release of Thicker Than Water and nine years before A Death in the Family.
• Regarding, the Time's Champion novel, it was intended to be the official final 6th Doctor adventure leading to his regeneration into the 7th  but was rejected by BBC Books in favor of Spiral Scratch. In the wake of Craig Hinton's untimely death, the novel was incomplete until the rest was written by Chris McKean
