DS Grant

DC Grant and her superior DS Nash were assigned to investigating the murder of Frank Foster in 2012.

The two detectives began their inquiries by questioning Sally Webster, who had found Frank's lifeless body with a bloody head wound on the factory floor of Underworld. When Sally proclaimed her innocence and mentioned that others had greater motives to murder the businessman, they went on to question Carla Connor. Carla admitted to having had a showdown with Frank shortly before his death (which almost resulted in him raping her a second time), but also denied murdering him and claimed to have managed to escape before things could turn violent.

Peter Barlow had gone on a drunken binge the night Frank was murdered, and his state when the returned the following morning clearly put him in the frame for the murder. He and Carla agreed to maintain to the police that he had returned home from a party at Nick's Bistro and stayed there all night. Peter was taken to the station for questioning by Nash and Grant after it was reported that he'd made drunken threats in the bistro to kill Frank. When his story was turned over with evidence that his credit card was used to purchase alcohol later in the evening, Peter admitted he was out all night and had no recollection of anything. However, he was released without charge.

Nash arrested Carla when a contract which signed Underworld over to Frank was discovered to be missing. Carla's fingerprints were also found on the whisky bottle which was believed to have killed Frank. Despite a police search of her flat, the contract was not found, and she was released on bail. Peter assumed that Carla was guilty and made a false confession in order to protect her.

Peter's fraudulent confession was eventually exposed, and following that Frank's mother Anne was discovered to have been the culprit and was taken into custody.
