  • It's an odd pair of definitions for this word. It could serve to characterize both the grifter and his elusive quarry.

    A cautelous is a wily man
    And cautelous too if wary.
    He’s certain to deceive himself
    And find that very scary.

  • "Believe't not lightly,--though I go alone,

    Like to a lonely dragon, that his fen

    Makes fear'd and talk'd of more than seen,--your son

    Will or exceed the common or be caught

    With cautelous baits and practice."

    - William Shakespeare, 'The Tragedy of Coriolanus'.
