Murder at Midterm

Bright med student Quinn Montgomery turns to murder when he learns that his penniless lover Holly Harris is pregnant, which would scupper his wedding plans with heiress Jennifer Warner. He arranges her death to look like suicide so after poisoning her takeaway he plants barbiturates in her hand, but Amanda points out the supposed suicide or accident is fake since there's no gelatin(due to the tablets) in her stomach, so her food had to be spiked. Dr Mark Sloane starts investigating every single detail till he knows enough to set a trap. This is a solid episode, quite compelling all through out.
