In Vino Veritas

I usually don't drink but tonight I shared a bottle of wine so some of this will be Bacchus-inspired.

Here I imagined fitting works of four genres into a chronologically linear sequence. (James Blish's After Such Knowledge is a three-genre Trilogy but not necessarily a linear one.) Of course, Poul Anderson has already fitted works of different genres into the non-linear framework of the multiverse. Hard sf character, Nicholas van Rijn, even visits the fantasy venue of the Old Phoenix. But a multiverse can incorporate anything, even what otherwise would be contradictions.

Seven Ways To Handle A Series Character
(i) Never show us his death. Thus, there is always scope for another sequel: Nicholas van Rijn: David Falkayn; Dominic Flandry; Gratillonius... As John Carter says, "We still live!"

(ii) If he does die, then leave him dead.

(iii) If this is a fantasy, then show us the hereafter or stage a resurrection.

(iv) Write stories set earlier. Doyle did.

(v) Explain that the character was not really dead after all. Doyle did this also. It is the death and resurrection myth in another form.

(vi) Contradict yourself. Harry Lime died in The Third Man the novel/film but is still alive in The Third Man the TV series. There are other examples.

(vii) Explain the contradiction with a multiverse.

Please don't tell me that I've missed anything!
