Implications/usage of "訳あり"


I am reading a work of fiction by a Japanese novelist and I found an
interesting phrase that I'm unfamiliar with, "訳あり"

In the story B launches a surprise raid on A's property. They talk a little
bit and B says A is irritating him, and A says;

> (A)「いらいらしたついでに、これがどういう事なのかペラペラ説明して下さると手間が省けるんですけどね……」
>
> (B)「悪いけど、こっちも訳ありでね」

What is this 訳あり? I looked in a dictionary and it says:

> Expression, Na-adjective 1. (having) special circumstances (e.g. problems,
> issues, advantages, flaws, defects, etc.)​

Is that the correct definition for this context? I only know of the "sorry"
"excuse me" sort of usage.

So what is B really saying? Can someone explain this sort of usage for 訳あり?
Maybe with more example sentences?




That dictionary definition is basically correct, but the important connotation
of 訳あり is "there are some special circumstances _that cannot be mentioned
openly_ ". People use this euphemistic word when explaining the details of
"circumstances" is risky, vulgar, tasteless, too direct, etc. For example,
訳ありの物件 is an euphemistic way of saying
[事故物件](https://jisho.org/search/%E4%BA%8B%E6%95%85%E7%89%A9%E4%BB%B6). 訳あり商品
([Wikipedia](https://ja.wikipedia.org/wiki/%E3%82%8F%E3%81%91%E3%81%82%E3%82%8A%E5%95%86%E5%93%81))
refers to discounted items due to broken package, etc (shops obviously don't
want to call them 欠陥商品).

If someone said 訳あり(の人), rather than actually asking for clarification, it's
often best to just guess what "the circumstances" actually means. Without any
context, a 訳ありの人間 by itself usually refers to someone who has some shady
background, for example a connection to a crime syndicate. In this situation,
B is clearly signaling he doesn't want to disclose who he is or why he is
there. Whatever his background is, he is implying he is not a mere petty
thief.

(I think 訳あり tends to be used as a no-adjective. 申し訳ありません has nothing to do
with this.)
