Explanation of answers

[bamberger]

Times 23984. I do try but its off putting when you have the answers but can't see how they work
Fish moves south along the coast. Sea Horse. Perhaps S for south inside shore (= coast) but where do the e& a come from?
Boy carrying bomb around fell behind. Lagged.Boy =lad but how does egg=bomb?
Frank, twenty-one, takes note. Natural. No idea how this works.
Devise the case for Jarndyce appearing regularly regardless. In any event . No idea I'm afraid
Bit of oil in motor encompassing velocity zero. Camphor. Again no idea.
Thanks

Boy carrying bomb around = LAD carrying Egg reversed i.e. GGE

[Aloysius535]

I ant explain the Bit of part but Oil = Camphor.

Motor is CAR around MPH (velocity) O (Zero)

[bamberger]

Yes but what has a bomb got to do with either an egg or a GGE?

[Aloysius535]

Devise = INVENT
Jarndyce regularly (i.e. every other letter) = ANYE

Regardless = INanyeVENT = In ANY EVENT

[Aloysius535]

Egg is slang for an aerial bomb

[bamberger]

Really impressed with the Jarndyce answer -thanks.
