Word Ladder - Part Two

spear

spreads

reaps

par

parts

patrons

arson

Did you mean "soar"? We need a 4-letter word after "arson".

Then "oar"

adore

boarded

dears

"dears" doesn't work after "barded" - you can't add new letters on the way down.  Let's make that "dread" and then "dare" works.

Next word: ear

crate

terrace

trace
