In posting the next installment of this series, I am pleased to be answering what has been an unexpectedly popular demand.  So, here again are some important "words to live by" from the master sleuth himself.
1) "It is my business to know what other people don't      know."
2) “Work is the best antidote to      sorrow.”
3) “Evil indeed is the man who      has not one woman to mourn him.”
4) “It is better to learn wisdom      late than never to learn it at all.”
5) “You can't play with edged tools forever without      cutting those dainty hands.”
6) “Any truth is better than indefinite doubt.”
7) “Jealousy is a strange      transformer of characters.”
8) "Dogs don't make mistakes."
9) “I have investigated many crimes, but I have      never yet seen one which was committed by a flying creature.”
10) "Our highest assurance of      the goodness of providence seems to me to rest in the flowers. All other      things, our powers, our desires, our food, are really necessary for our      existence in the first instance. But this rose is an extra. Its smell and      its color are an embellishment of life, not a condition of it. It is only      goodness which gives extras, and so I say again that we have much to hope      from the flowers.”"
