Whenever

Nasty Uncle kills Nice Uncle, gets Bob the Footman to take the blame and Emily gets away to the future in the Time Machine.

She has adventures in 1940s Blitz-torn London where she picks up a couple of friendly passengers and they move to 2010 where Droids rule.

They pick up one of the more intelligent Droids (Z1991 = Ziggie) and bump up against The End of Time where the only creature left is Hoombean (Human Being) who is barely able to communicate.

So they all return to the 1880s where Emily is just in Time to save Nice Uncle from death and Bob the Butler from being hanged for the murder.
