13.2.43

pratipannaṃ rātrau sattracchannāḥ samāgame śastrarasābhyāṃ ghātayeyuḥ //

When the enemy is fond of wealth or women, he may be beguiled at the sight of rich and beautiful widows brought before him with a plaint for the recovery of a deposit kept by them in the custody of one of their kinsmen; and when he comes to meet with a woman at night as arranged, hidden spies may kill him with weapons or poison.
