"Sherlock Holmes and the Mystery Osborne House" - trailer

[Answl82]

Does anyone know of any decent walkthroughs for this game? Looked everywhere. I need to find out, after getting given the bonus puzzles, how i get to get more points to allow me to play the last puzzle. Without being able to complete it as 'i dont have enough points' I am unable to advance in the game. Ive tried replaying all the puzzles in the archive and I dont earn one single new point - HHHHHEEEELLLLPPP!
