The final Modesty Blaise book is a collection of five novelettes and novellas covering the full span of Modesty Blaise's career, from the early days of the Network to Modesty and Willie coming out of retirement for one last caper. It's a fine collection for long-term fans, providing both new stories and closure for several long term story threads from the series. I don't think it's the ideal place for a new fan to start, because the references to events in earlier books may act as spoilers for those who haven't read those books yet, and the impact of the title story will be blunted for those who haven't had several books in which to become attached to the characters. It is however possible to enjoy these stories without ever having read any other Modesty Blaise books or the comic strip, and while ideally new readers should start with an earlier book in this series, they shouldn't be put off starting with Cobra Trap if it's the only one readily available to them.
The stories are classic Modesty Blaise. Once again O'Donnell demonstrates the appeal of a heroine and hero who are quite willing to go outside the law, but never to step outside their own moral code. For Modesty and Willie the ends do not justify the means. You know that the villains will lose in the end, but there will be no easy solution, and the good guys may well pay a high price for their victory. The stories are often hilarious, sometimes heart wrenching, and always thrilling to read. Some of the stories rely on the most outrageous coincidences, but with this level of writing there is no problem in suspending disbelief. This is a beautifully written and wonderfully entertaining book, and the final story is a bittersweet but emotionally right conclusion to the series.
