Jeez, this isn't an easy one. Carbon monoxide isn't detectable by the olfactory nerves (your sense of smell). Is there a 24-hour Walgreens/Walmart/something in your area? You can usually get a cheap CO detector, and if the place is close enough to home, it wouldn't take too long to fetch one. It's either that or stay up and constantly check everyone throughout the night.
is it interior or exterior door? The screws that hold a common knob (Kwick-Set) are on the side with the lock button. these could have come loose (the plate (the piece closest to the door) would have come off too) otherwise the knob and just the knob came off. you will need to replace the whole thing. it is assembled to not be repaired, in this instance. The new assembly will cost between $15 and $25. it will include instructions. Typically about 4 screws and 20 mins if you have any dexterity at all.
It is probably just a backdraft of the chimney due to the flue cooling off. Hence the smoke smell in the house. It is not that much to worry about, a fire that is lit will heat the flue back up so that combustion gases exit the chimney again normally. If you have birds, they are the first to notice it because they fall off their perch. Canaries were used initially in coal mines to determine if the air was good enough to breathe for humans. Yes, it does raise the CO and CO2 levels in the home, but normally not enough to be a concern.
I'd just put it out and explain why in the morning.
