HYPOTHETICAL: In a criminal trial, your client admits to you (the attorney) that he committed the crime. He wants to put his sister on the witness stand who will lie and provide him with an alibi that places him in another city at the time of the crime.

QUESTION: If the client's sister came to you (the attorney) before the trial and told you that your client committed the crime and the prosecution found out about this, could the prosecution call you as a witness at trial and ask you what the sister told you?
