Thursday's Daily Mail Prize Crossword

[Jock13]

Please could someone confirm 12 across?
Clue is ; Shrill whistle's meant to include everyone except Henry, 7 letters.

I think it is CATCALL, (shrill whistle) but can't see how it fits the rest of the clue.

[bibblebub]

meant to include everyone = catch all

except henry => remove the H

[sandyRoe]

include everyone...catch all...except Henry...remove the H ...catcall?

[Jock13]

I see it now - thank you, bibblebub and sandyRoe, for the speedy reply.
Clearly, my little grey cells are on the wane!
