Accused of stealing a Fire arm and I need help?

Ok, My Boyfriend and I own a cleaning company and one of our clients has accused us of stealing her Firearm.

I never saw the firearm or even heard of a firearm until she called me asking if I seen it. My husband did see it and that's the first I heard of it. He said he removed the firearm along with other stuff from on top of the entertainment stand to dust. He put everything in a basket on the bed. She came in there and was going through everything in the basket so he assumed she moved the pistol because it wasn't there when he put everything back. Well a week or so later she called again and asked if we were sure we didn't see it because she has searched the house up and down. Again we told her no. Then a week later a officer called us in for questioning. We were supposed to meet him today at 1pm But, I have been calling lawyers all day and they have all said not to speak to the police unless I have a lawyer. So I called the officer and left him a voicemail that I am going to look for a lawyer. My question is.. Where do I stand now? Does he have to give me time to find a lawyer? Can he arrest us? Beings that I never even seen the firearm will just my boyfriend be the main one accused? I've never had to deal with anything like this and I am kinda freaking out because I did nothing wrong.. And I don't want him arresting me just because I want a lawyer.
