"Indirect questions do not close with a question mark but with a period. Like direct questions they demand a response, but they are expressed as declarations without the formal characteristics of a question. That is, they have no inversion, no interrogative words, and no special intonation. We can imagine, for example, a situation in which one person asks another, 'Are you going downtown?' (a direct question). The person addressed does not hear and a bystander says, 'He asked if you were going downtown.' That is an indirect question. It requires an answer, but it is expressed as a statement and so is closed by a period, not a query." (Thomas S. Kane, The New Oxford Guide to Writing. Oxford Univ. Press, 1988)

Indirect questions in English

If you want to ask a question that is quite sensitive, try using one of the indirect phrases below:

Can you tell me…
Could you tell me…
I'd be interested to hear…
I'd like to know…
Would you mind telling me…

These questions are followed by either about, a "wh word" or if. Then you add the subject, then the sentence.
