This book was very light on the plot/mystery element. Most of it consisted of Simmy dreading the approach of Mother's Day because she lost her stillborn child on Mother's Day several years ago and can't bear to be reminded of it. Which is totally understandable, but it's a really dumb idea to set yourself up as a florist if you can't bear to think or talk about Mother's Day!
There was also a weird subplot that ended up not being one - Bonnie, Simmy's teenage assistant, has a mysterious cold which just won't get better. Paragraph after paragraph is devoted to Bonnie's illness- it becomes such a major part of the book that I expected it to have some great significance, like Bonnie discovering it's really an allergy to flowers so she has to give up the job, or worse still, that she has some kind of serious illness. Instead, the cold eventually gets better and that's the last we hear of it. Ok, I know that in real life, people do get extra-bad colds and other people worry about them, but in a novel, I don't expect something to take up so many pages unless it is going to contribute in a major way to the storyline. Bonnie's cold didn't add a thing to this book except that it padded out some pages.
When the murder is committed, Simmy decides one of the suspects must be innocent because she has such a nice best friend. And when Ben & Bonnie refuse to rule the woman out on that basis, Simmy gets upset that they are now 'on different sides'. It seemed an incredibly juvenile attitude for a woman of nearly 40. And several times, she talks about herself and the two youngsters as being like the Famous Five. Most of the time, teenage Ben & Bonnie seemed to be far older than the rather juvenile Simmy.
While the trio's research does raise one or two helpful points, the mystery is finally solved when the guilty party (for a reason that is never made clear) suddenly decides to confess in a dramatic scene.
Overall, I was really disappointed in this book - it started off so promisingly, yet fizzled out partway like a damp squib.
