There are four main cases to work through, in each one you ll find yourself travelling between crime scenes, private clubs, residences, 221b Baker Street and Scotland Yard, scouring for clues to analyse, interviewing key characters and filling your casebook.
You can piece together flashback sequences in a vaguely Vanishing of Ethan Carter style, or switch to Sherlock s version of Assassin Creed s Eagle Vision, where all turns monochrome allowing tiny details to reveal themselves to your razor-sharp intuition.
The plotting might not always be convincing – even by the standards of the BBC TV run – but it s good enough to keep your interest through the twelve or so hours it ll take you to push through.
At times it s unnecessarily pernickety as well, refusing to let you enter a location you know damn well you need to enter, and all because you didn t turn some piddling flyer over to see a note on the back.
It s telling that so many of these sequences can be skipped with a single button press and without any noticeable penalty.
Early on I was sure these things would doom The Devil s Daughter to a fairly low score; it s high time the series left such amateurish stuff behind.
