Query: A disappointing entry into the Death on Demand series

I always eagerly await the next DEATH ON DEMAND book. Annie's usually funny, Max adorable, and Laurel maddening. However in this entry, nothing much seems to happen and those beloved characters fail to come alive. Annie's best friend, Henny Brawley, has been injured, but it also the prime suspect in a murder. That alone should've made for a great book. But Ms. Hart couldn't put it together this time. I like the references to other mysteries -- I've found a lot of new favorite authors through the mentions in Ms. Hart's novels. Please make the next one better!
