Well,
If you want to be a good detective, you should read the Sherlock Holmes stories. And kind of remember all the stuff that Sherlock does in the cases.
And if you want some equipment, You could buy a CSI Kit. They have evidence kits, handwriting kits, and they have the big Field kit. the field kit has all the stuff you need to solve a case. (if you want to know where to buy them look on websites that sell things. or look on the shelves at retail stores.)
