Q:

What's the meaning of "cross any of our desks"?

So I saw this line from a TV drama (again) and couldn't understand it. Here is the line:

But Michaela Stone remains a person of interest in the most perplexing investigation ever to cross any of our desks.

What's the meaning of "cross any of our desks"? I was guessing "according to our records" or something like that.

A:

Basically it's a variation on the idiom
"To cross one's path"
Which means "to encounter". The author substituted the word "desks" for "path" to emphasise the idea that the encounter happened at work.
