Read a few pages. Nice clear writing and natural dialogue. One comment if you're looking for feedback is about the V.O. Now a lot of bullshit is spoken about voice overs and their redundancy. I actually love a good V.O if they add to atmosphere and get over important or interesting information. Thing is about yours, your protag is talking about his dubious investigations and his split with an ex-partner. Then when he turns up at the house, we re-discover all that information in their exchanges. So the V.O is redundant. I'd try to keep the V.O. to supplementary info rather than stuff that's already obvious.
Sorry to focus on the one negative but that's the nature of feedback. Overall i enjoyed the read so far.
