Mage Wars: Beastmaster's Pet
I have the game and tried playing the first case, but was a bit confused about some stuff, mostly what it meant to visit places and following a lead.
I know what you mean. If you have to visit three places to find out (and corroborate) a single piece of information, is that following one lead or three? It doesn't bother us, because we're just happy if we solve the mysteries - we don't try to beat Holmes. However, what we do is class those multiple visits as one lead. It's a bit vague sometimes, but the answers also give you free visits (places that don't count as one of your five a day).
(The 'five a day' joke might not be applicable in every country).
