The Best Mistake Mystery

by Sylvia McNicoll

Published 7 January 2017
Some people count their blessings, but dogwalker Stephen Nobel counts mistakes.



Dogwalker extraordinaire Stephen Nobel can get a little anxious, but his habit of counting the mistakes he and everyone else makes calms him. His need to analyze gets kicked into hyperdrive after two crazy events happen in one day at school: the bomb squad blows up a backpack and someone smashes a car into the building.


To make things worse, that someone thinks Stephen can identify them. Stephen receives a threatening text. If he goes to the police, his favourite dogs, Ping and Pong, will get hurt. The pressure mounts when his new best friend, Renee, begs for Stephen's help. Her brother has been charged with the crimes and she wants to clear his name.


Is it a mistake to give in to dognappers? How can he possibly save everybody? To find out, Stephen will have to count on all of his new friends.

Noble Dog Walking takes care of pets, even if they slither.

After losing Ping and Pong as clients, too, Stephen and Renée pin their last hope on gathering all the suspects at the animal shelter, and a real Cat-astrophe ensues.

Five-year-old Pearl claims that a pirate stole the rare Blushing Diamond. But everyone's a pirate on Halloween.


Dogwalker Stephen Noble has been recruited to walk his five-year-old reading buddy, Pearl Lebel, to and from school while her mother is away and her father is ill. He's sure that this will be easier than walking canine clients Ping and Pong - until Pearl locks herself in the house, runs away from home, and loses her family's rare pink diamond ring.


When Pearl claims that a pirate took the ring, Stephen and Renee are on the case. But the more they discover, the more it feels like everyone is a suspect. With Pearl annoying them every step of the way, will they be able to solve the mystery before the ring's scheduled appearance at the Brilliant Diamond Show?
