( the 2nd sentence is correct, isn't it? ) |
Yes. The 2nd part, "did he find he'd left..." is OK. :D
he did (in fact) find.... (
did refers to 'it's a fact'; used for emphasis)

did is moved to the verb position)
Not until X
verb Y
X = he had arrived home
Y = he find he had left the key....
If we add a
verb, then 'did' becomes ungrammatical:
It
was not until he had arrived home
did he find....
Ungrammatical
:D
By the way, the original sentence is not grammatical to me. I prefer:
Not until he
had arrived home did he find he had left....
:D
