I think it may have been the first time ever that the teaser doesn't have Horatio in it. For some reason, I hate him, and I only watch the show for the story.
The beginning was interesting with Delko & Alexx trapped in the fire and forcing them to take refuge under a tarpaulin.
Two bodies a male & female are found in the fire, both crimes unrlated.
The woman looks like she was beaten to death & her killer may have started the fire.
The dead guy was killed by a dog who somehow accidentaly set the gun off. The dogs owner wanted to take the blame so that his dog wouldn't have to be put to sleep.
