First of all, props to Disney for making a faithful representation of Sherlock Holmes in mouse form. I was too innocent (and too traumatized by the world's creepiest bat) to see it when I watched this as a child, but Basil has all the signs of being manic-depressive and nursing a cocaine habit.
|Basil is depressed (note the violin).|
|Basil is manic (note the pupils...and confiscate the gun).|
Anywoodle, I do have a couple of observations regarding The Sign of Four, other than its shocking lack of crime-solving mice.
When the story picks up, Watson has been living with Holmes for years and is starting to get used to his peculiarities. What he CAN'T seem to get used to is the sight of Holmes injecting himself with cocaine and/or morphine, which seems to be a regular occurrence.
Three times a day for many months I had witnessed this performance, but custom had not reconciled my mind to it. (p. 91)Poor, sweet Watson. He's just a moral, upright
I suppose that its influence is physically a bad one. I find it, however, so transcendently stimulating and clarifying to the mind that its secondary action is a matter of small moment. (p. 91)
But this story does see Watson finding love with the lovely Mary Morstan. And they are disgustingly adorable. Even Holmes begrudgingly admits as much as he reaches for the cocaine bottle.
|In mouse form, she's quite out of Watson's league.|
