Begins brilliantly, as the ensemble begin to show their acting abilities. The uncommon opening interviews are a nice change from the genre formula and contain some subtle humour and entertaining ham-acting. One feels in comfortable, yet somewhat novel and exciting, waters with the family of suspects, the isolated manor house and the eccentric private detective.

However the novelty is somewhat its undoing, as we are aware very early on of some of the fundamental facts of the crime. From that point the subsequent reveals and deduction, combined with Marta's 'can't tell a lie' contrivance, become a little tedious and drag out the move beyond an appropriate run-time.

Fun to start, slow to end.
