The Interrogation

The Interrogation by Shikhar Dixit (a Short Story Contest entry) 

Detective Rappaport decided Gordon Tho's guilt the day they met. A weird man with difficulties socializing, Tho brought down Rappaport's wrath. The detective "interviewed" Tho in a small, tight and hot room after Tho admitted he was on antipsychotic medication that overheated him.

The detective took a break every hour. Tho sweated through his fleece shirt within one hour. Requests for water were ignored.

After seven hours, Rappaport had a confession.
