The Spider

An ex-cop who is now a private detective is hired by a woman to be the go-between in retrieving an important envelope from her partner. The detective has the partner come to his apartment to give him the envelope, but someone sneaks into his apartment and strangles her while the detective is in another room. Fearful that the police will suspect him of the murder, he brings the woman's body back to her own apartment, but the police find out and suspect him of the murder anyway. (imdb)
