Hehe. I told you you were attempting something difficult
I did have to go back to the prologue to get my bearings when you had that little jump forward, as I didn't really think of the prologue as being connected to the first chapter (until I got down to the end). I've been trying to think about what could make these little out-of-sequence jumps clearer to the reader . . . besides a formatting change . . . maybe you could try a tense change? BTW these suggestions of mine are pure conjecture, as I've never written anything like this before
So the tenses...you have a bit of switching here and there between past and present (w/i a sentence or paragraph), which I don't believe was intentional, so you might need to go back and do some editing. Anyways, my (probably somewhat crazy) thought is that you could have the "now" events in present tense (so, the prologue, and when the MC gets back to wondering about the business card) and the other bits in past. Again, I don't exactly know how it would all work out, but it's an idea, and it might help readers get the "flow."
'Course I might read on and see that won't work out...but it popped into my head so I just thought I'd share.
