Do you suspect that he is cheating?

Why do you suspect him?

I wonder what his plan is.

I couldn't find the receipt. I wonder whether I can claim it.

I wonder whether buying online requires ordering a lot.

I have never doubted him for even a single fraction of a second.

I wonder whether they are camouflaging their identities and going undercover.

He deceived us so seamlessly that nobody suspected, but it turned out that the plan failed.

The committee wonders whether the letter of recommendation from the reference person is genuine or not.
