A Man of His Word Session 2

Having been tasked by local crimeboss Booker with helping Matheson Ratch repay the dept that he owes, gnome mage Eric Smith, halfling thief/child impersonator Terry Grey, and consulting detective wolfman J. Wolfington III explore the Tenement building Ratch recently bought. While on an upper floor Smith was attacked by something small and invisible. Grey and Wolfington came to the gnome’s aid, and Grey incapacitated the beast with a potato. Wolfington stabbed the beast (lightly) with his sword, revealing visible blood.
The Halfling examined the beast further finding a small leather collar with a piece of glass attached. When removed the beast became visible, revealing it to be a mangy mongrel of the streets.

Hearing the commotion Ratch left his room and discovered the group. Terry pretended to be a small boy who lost his dog in the building. He asked what they were doing in his building, since no one lives there because of the ghosts.  Ratch let the group search the building, starting with the basement.
The Three proceeded down and were immediately attacked by invisible pigeons. Between some fancy fistwork on the part of the wolfman, expertly cast fireballs from the gnome, and wicked wicker basket wielding by the halfling, the pigeons were dealt with and their enchanted collars collected.
Terry found the dog again and calmed it, as the other two searched for clues. In the Basement, Eric discovered a small grime-covered window leading into an alley. After climbing through he found a small pile of ash from a pipe.
J. Wolfington III deduced that a street-witch must have been hired to enchant these animals. But for what purpose?

The two sleuths went back up stairs where Terry had patched up the wounded dog and named it. J. Wolfington reached down to pet the dog, when the dog, remembering that the wolfman had stabbed it previously, snarled and lashed out, biting off two fingers of the wolfmans right hand.
Acting quickly, the gnome mage cast etheric Inferno, cauterizing the wound, and the halfling cleaned the hand and dressed it. They then hurried the wolfman up to the attic to continue searching for clues.

The Attic had been converted into more rent-able space, by hanging sheets across the room. Eric quickly ran through the attic looking for any signs of invisible attackers. With none appearing, the party continued to look for clues. Two chests were discovered under a window, one empty  the other was full of junk. Examining around the window, another small pile of ash was found along with a print of a cheap  boot.
As the three investigators discussed this new evidence, J. Wolfington noticed the dog had come with them.
The Wolfman drew his sword, but Terry (who had grown attached to the mangy mongrel) steped in the way. After a short scuffle the dog ran away with less of a tail that it had before, and the halfling and the wolfman had decided to put their fight aside. For now.
