This crazy string of events all takes place in the first few minutes of this remarkable, six-episode series created by Hans Rosenfeldt, the Swedish writer behind the original version of The Bridge.
Despite her meltdown, Marcella continues investigating a brutal series of murders that has the city in a panic, and she reconnects with a cop (Jamie Bamber) - who is investigating the heiress' death.
Complex, ultradark, and filled with more red herrings than an Agatha Christie novel, Marcella is a unique, powerful crime drama.
