5 Mysteries from 2009: a Book Map or Inspiration Board

In 2009 I read 5 mysteries which were the first in a possible series. If the authors of the books pictured below do decide to write sequels, I will be looking forward to reading about: the narcoleptic detective from the Little Sleep, the precocious teenage sleuth from the Sweetness at the Bottom of the Pie, Delhi's finest detective from the Case of the Missing Servant, Chet the Dog and his human partner from Spencer Quinn's Dog On It and the lawyers whose offices are at 221 B Baker Street where letters to Mr. Holmes are still received, and answered, in the Baker Street Letters.

PS: if this blog had an editor, he/she would have helped me with that first sentence. Rewrites welcomed.
