“Is there any danger in this?” It is very hard to tell with just a description from you, my advice would be to contact a Chimney Safety Institute of America chimney sweep http://www.csia.org/ and go to the home owners section there you will be able to find a local Certified Chimney Sweep in your area, they will be able to come out and look at the whole chimney system. I do not know what each chimney sweep would charge but you can ask them what an inspection costs. They will be able to tell you if the chimney is lined, dirty, working properly, and if it is safe and if not how to fix it.
