let in flush with the pannelling

[vil]

Dear teachers,

Would you be kind enough to tell me whether I am right with my interpretation of the expression in bold in the following sentence from Huxley’s “Crome Yellow”?

It was just an ordinary door let in flush with the pannelling.

flush = so as to be even, in one plane, or aligned with a margin

let in flush with the pannelling = placed on the same level with the pannelling of the wall so as to make the door quite untoceiable

Thank you for your efforts.

Regards,

V.

The correct spelling is panelling.
'let in flush' sounds strange to me.
I'd say, 'installed flush with the panelling'.

Typo for "set in"?
