## Solution
The first part of the the message is looks like _JSFuck_, however going to that is a rabbit hole.
We see that there seems to be an "unnecessary" lines at the end. Since this problem was named __Read Between the Lines__, we do just that and see that each line has `spaces` and `tabs`.
We convert these two `0` and `1` to get the flag.
```pythonfound = []with open('message') as f:	for e in f:		e = e.replace(' ', '0')		e = e.replace('\t','1')		try:			found.append(int(e,2))		except Exception:			pass
flag = []for e in found:	try:		flag.append(chr(e))	except Exception:		break
print(''.join(reversed(flag)))```
