Heathcliff Lennox and his good friend retired Scotland Yard Inspector Swift have been asked to come to London and help with a murder investigation. That is unusual because in the past their investigations have not always been welcomed by The Yard. Lennox is a former WWI flying hero. He comes from a well known family. And he is handsome. So, if one were seeking a hero, he is perfect for the job.At an exclusive dinner in a private club, a gentleman has died. His death was especially gruesome. It is believed the man who died was responsible for an explosion which killed 8 people. Everyone else at the dinner were relatives of those people who died in the explosion. The suspects are many and right at the scene of the crime.This series is always filled with a good mystery. Lennox and Swift are good investigators. Each has their own style. Swift is pedantic and precise. Lennox asks questions, looks at places and people and uses his powers of deduction and commons sense.And there is always food, atmosphere and humor.This investigation is a difficult one. There is sympathy for everyone involved. But, Lennox and Swift move forward at a steady pace.These books are wonderful. The character development is terrific. These are complete people. Even the lowest secondary characters add to the story. The plots are always well done and draw the reader right into the period between the Great Wars. We are all in it together looking for clues and asking questions.I loved this book. I have loved every one of the Lennox series.
