Clubs are trumps, declarer claims with E on lead, and thinking declarer has a trump and 4 spades we table our hands, then see his diamond, I'm on lead and have one, 2 in fact and one is bigger than the 9.
Now as I recall you can't normally take a winning finesse after a misclaim, Q♠ is onside.
What I'm not sure of is if the EW hands have 7 spades and a diamond left between them after the diamond is played at trick 9 so the drop or any pin cannot work, what happens next, I'm comfortable with there being a losing option you must take if the remaining cards are 6 spades and 2 red cards, but are you required to miscount if there is only one non spade out ?
