Jane Croft: The Baker Street Murder is, for the most part, pure hidden object. There is the occasional mini-game thrown in to mix things up a bit, but the number of hidden object screens far outnumbers any other aspect of the game.
Jane Croft is a crack-shot homicide detective who has a new case to solve. It seems the local millionaire has been found dead, shot six times, in a back alley behind 221B Baker Street (if the location doesn't sound familiar, you need to familiarize yourself with some classic crime novels). It isn't long into the investigation before Croft uncovers several potential murderers. It seems our murder victim liked to spend the night on the town and with a lot of ladies, despite his long-standing marriage. It also seems he has built up quite a large debt at the local casino. Naturally, the wife, the casino owner and the mistresses are all murder suspects, but its going to take crack investigation techniques, which apparently involve digging through rooms of oddly placed and proportioned junk, in order to find out who actually killed the victim.
As I said above, most of the game is hidden object. More often than not, you will be presented with a screen and a large list of items to click on and find. Once cleared, you will leave the scene and find another one where you will perform the same basic steps.
The mini-games that are thrown in to spice things up are everything from a cup-and-ball game to figuring out the key code to an electronic door lock to mixing chemicals to crossword and jigsaw puzzles. While not a lot, they do tend to break up the hidden object parts of the game quite well and keep the overall experience from getting tedious.
