As a detective you will often be thrown into positions where you have got to drink.
Now a drinking detective is but a poor worthless creature, as a rule. Then what are you going to do?
Here, again, no rule can be laid down. You must be guided by your constitution, by your conscience, by circumstances.
If you allow liquor to get control of you be very sure you will not be able to control your man. To think this is to make a great mistake.
Great criminals are seldom drunkards. If they lead you to drink, it is only that they may get the best of you in some way or other.
Still, to refuse absolutely, would be to excite suspicion, which leaves you between two fires, as it were.
I can only warn you—I cannot dictate.
The best way is to plead that liquor never agrees with you—too much never agrees with any one—and stick to temperance drinks.
If you feel that you must drink, make your drinks as small as possible and as few.
