More than an examination of a mere thieves' guild, the Solomon Guild is a window looking onto an entire fantasy criminal organization spanning all manner of criminals. It is, without a doubt, the most detailed, most thorough, and most engaging such product I have ever read. If you want an entire organization of adversaries discussed in painstaking detail from vaunted criminal masterminds to the lowest of the low on the criminal totem pole, you owe it to yourself to pick up this book. This product can easily be dropped into any existing fantasy setting or campaign, making it a valuable asset to any fantasy GM.
