Dear Jay - This is an engorged female hard tick (family Ixodidae); possibly a brown dog tick,  Rhipicephalus sanguineus - see http://tinyurl.com/amkar7j for an image. This appears to be the only hard tick species that can establish a breeding population indoors - see http://tinyurl.com/7bm82h3 for a fact sheet with more detailed information including control recommendations.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
