This isn't wise

Sierra paced a few steps away from the vampire afraid she would be found out. Her body hid between two buildings in an alley that didn't have a dead-end. A vampire was sucking blood from a human in broad daylight and no one stopped him. Could it be that the woman was also bought by a vampire?

From her appearance, she must be already an adult. However, she wasn't someone she saw in the fifth district. In fact, the fifth rankers weren't numerous. Everyone knew them, even if by appearance or name. The woman's traits didn't look like anyone in her memory. Was she someone of lower rank? But lower ranks weren't allowed in the higher districts unless it was important and urgent.
