Word squares have been around for literally thousands of years (the oldest known example has been found in ruins across the Roman Empire, including the walls of Pompeii). Each word square is a group of words, all of the same length, arranged so the word in row one is the same as that in column one; row two the same as column two; and so forth. Easy word squares are four-by-four; much harder are eight-by-eights; given a few letter clues, the goal is to fill a perfect word square. In this book, puzzle master Alastair Chisholm has produced 201 brainteasers--from Delicious to Vicious--that will stretch your vocabulary and challenge your puzzle solving skills.

Using the latest modern technology available to forensic science, crime scene investigators answer questions others never even thought to ask. This book contains more than thirty fascinating modern cases of forensic detective work. Genetic fingerprinting, blood splatter analysis, laser ablation, toxicology, ballistics analysis - the whole range of forensic techniques is featured. The investigators trust only the evidence to speak for those who cannot speak for themselves: the victims. The cases featured include: - Tommie Lee Andrews, the first person to be convicted as a result of DNA evidence, for raping a woman during a burglary; - Jeffrey Gafoor, convicted of murder in 2003 when crime scene evidence collected twelve years previously resulted in a match with his nephew; - Richard W. Rogers, convicted of the murder of two of his numerous gay male victims, through vacuum metal deposition, technology which saves fingerprints from plastic bags; - Dr. Sam Sheppard, the murder trial based on blood evidence that inspired the TV series The Fugitive; - Edwin Bush, the first murderer in Britain to be brought to book thanks to an identikit picture; - Derrick Todd Lee, the Baton Rouge Serial Killer, only nailed by DNA evidence after a flawed FBI profile led big-shot investigators astray. These cases - usually successful, but also sometimes dangerously flawed - offer a remarkable insight into real-life scene-of-crime investigation.
