Grand Secretary Howls at the Moon

Queer noises have been coming from the villa of one of the Grand Secretaries during the night lately, increasing in intensity and strength with each passing month. Initially you put it down to some intricate playtime with one of his concubines, but recently it has begun to dawn on you that there is a remarkable connection between the lunar phase and the noises. A spy sent into the garden on a full moon night returns with disturbing news: The Grand Secretary spends his nights standing in his garden, howling at the moon.
