This book should be very helpful for translators and interpreters working with criminal and police terminology. It appears to be an out-of-print book from Tachibana Shobo, and is likely no longer in circulation, as it's being sold for over 30,000 yen on Amazon, Rakuten, and Mercari. As the photos show, there are pencil underlines, etc., so please purchase only if you understand that this is a used item.
