Missing Check from Checkbook question

My HOA hires a bookkeeper to create checks, reconcile the bank statement, produce reports for the board and serves at the leisure of the Treasurer. The former bookkeeper was removed due to strained relationship with the Treasurer and I have filled that role. Upon inspection of the check register, the last check is missing with a note that it was given to the President. No explanation given as to why and the former bookkeeper and President are close friends.

The check has not cleared the bank and we require dual signatures (President, Treasurer, unknown other(s))in place to sign checks. Our HOA has a business meeting tomorrow night. How do you think I should bring this up? I was thinking of just giving the budget report to everyone and saying something like "Check #### is missing from the checkbook, does anyone know where it is?"

If you think it should be handled another way, I would like to hear from you.
Thank you in advance.

for a few $$ have the bank issue a 'stop payment' on the check in question

voila....problem solved
