This is the first book of the seven-book series...

When Johnny Naples entrusts Tim Diamond with a valuable package, he is making an enormous mistake. Tim is probably the worst detective in the entire world. The very next day Johnny is dead. Tim, gets all the blame and his younger brother Nick, gets the package. But guarding it becomes difficult with all the crooks in London looking for it...

Yet another perfectly written book by Anthony Horowitz! This book was my personal favourite out of the Diamond Brothers series. This was one of Williams´s top picks as well, and he says it´s "very funny and enjoyable to read. Anthony Horowitz makes writing look easy". I couldn´t agree more! Perfect short (ish!) book for a great read.
