Trouble in the inn (5th edition adventure part 6)

Continued from here.

After the inn went silent, Oldbook returned to the common room. He took care to do everything quietly, knowing that innkeeper has a light sleep.
Sneak test. If the result of the test is under 10, innkeeper will wake up. Between 10 and 15 Oldbook will have disadvantage on all actions since he can do so mush without making noise. On more than 15 innkeeper will not wake up no matter what our hero does. I rolled 14, so disadvantage it is.

Search behind bar found no clues (failed investigation test), so Oldbook decided to search basement. Basement was locked (failed Sleigh off hand test) but our hero remembered seeing the key behind bar (successful perception test).
Bard unlocked the basement and started looking through it, but all he found was a guard dog!

Dog jumped at our hero, and knocked him prone, biting his left hand. Our hero found himself in disadvantage again. Further more, Innkeeper woke up by the noise of the struggle, and will come to basement in (2d6=) 5 turns.
It took 3 turns for our hero to hit a dog with the rapier and kill  him. Heavy bleeding himself, he tried to hide in the far corner of the basement.

But innkeeper came with the lamp and noticed Oldbook (failed stealth check VS. innkeepers passive perception of 10).
- What are you doing here? - innkeeper asked.
- I just wanted to have a midnight drink of wine when your dog attacked me - bard replayed.
Will the innkeeper buy this? (persuasion test, difficulty 10 with +5 modifier. Rolled 5 so right on target). It seems yes but....
- I will not have your kind making troubles in my inn. - said the innkeeper. - Pack your things and get out. But not before you pay me for the dog. This kind of trained guardian cost me 25gp.
Oldbook had no choice but to pay for the dog and to leave the in. 25gp were almost all the money our hero had with him. In his pocket there were only 11sp left. Furthermore, he was wounded, and he really needed some rest.
Since he was not welcome in the inn any more, bard used his song to seduce a local widow who allowed him to spend the next night in her home (successful performance test).

As our hero found no clues about innkeepers treason, he decided to do as advised earlier and to follow his initial plan. So, he took into wilderness, looking for kobolds.
