The wording of the question suggests that you are the target of a criminal investigation. As a general rule, you are best served by contacting experienced criminal representation before agreeing to an interview in a situation where you are a target. There are potential dangers of self incrimination present in a target's interview by law enforcement.
You have an absolute right to refuse to talk with a government investigator at any stage of the investigation. I suggest that you contact a criminal attorney experienced in white collar crime. That attorney should contact the investigator and advise that he/she is representing you and that all contact with law enforcement should come through that attorney.
Working with your attorney, you will be able to make an informed decision of how to proceed in the investigation.
