BeTrapped! 

Betrapped! is an interesting puzzle/whodunit game.

You will play Scottland Yard Chief Inspector Parker, who must solve a murder case. In order to do that you will have to go through a big vessel's rooms disarming traps, talking to characters and finding clues.

To disarm traps you will play a puzzle that reminds of Minesweeper with colors that show the amount of traps next to every location in the room. When you locate a trap you can disarm it and watch how it works: poison, bombs, falling lamps, guns, and more. After you cleared a room, you can start searching for clues that include documents, keys, and secret compartments.

From time to time you will be able to speak with one of the suspects and ask a few questions that together with the clues will help you solve the case.

Betrapped features a good amount of levels (37 rooms which connect with each other through a map), and two modes: Adventure and Puzzle. Its interface is really neat, with nice three-dimensional graphics, and good incidental music and sounds.

If you enjoy whodunits and puzzles, you will certainly enjoy this one; you can get a 60 minute trial for free at the developer's site
