S4·E8 Big Topped

The news that Sandra's father, a DI, killed himself while under investigation for corruption, throws into doubt everything she believed in.

Her mother, Grace , is in hospital following a stroke, and she wastes no time in confronting her, but she doesn't get the answers she's looking for.

Unfortunately, her father's service records provide Pullman with some revelations she may never come to terms with.

Meanwhile, Christy Berlin asks the team to look into the death of the man she's recently discovered was her biological father - ringmaster The Great Miraculob. But will the investigation at Spingles Circus be enough to distract Sandra from feeling betrayed by her colleagues?
