Having reminded myself this thread exists, the other thing I'm playing at the moment is
Layton Brothers Mystery Room; a spin-off from the Professor Layton series where you instead follow the exploits of the professor's brother, a detective in Scotland Yard, as he and his assistant solve murders.
The presentation and dialogue is a lot like the Professor Layton games but the gameplay is much more like the Phoenix Wright series (or what little I've played of them anyway). You get the basic story of the crime, victim and suspects then you can investigate the murder scene recreated in the Mystery Room of the title. You move back and forth between that and the questioning of suspects until you've built a case then you go after your prime suspect and try to break them under questioning.
I've only done the first case but it's pretty good fun so far and is very well presented with lots of nice effects (e.g. your questions to the suspects show as accusatory arrows chipping away at an armoured heart which gets more nervous as you come closer to the truth). It's especially good fun for my commute as me and Mrs B can play it together, but that's specific to me I assume.
The first two or three cases are free then you need to pony up for the rest so you can give it a good shot without spending any money.
