Suresh Parekh

Suresh Parekh was a waiter at a restaurant in Bombay, India. In 1816, he saw what he thought was a ghost. It was actually the First Doctor, who was drifting through time incorporeally after an attempt to fix his TARDIS failed. The "ghost" reappeared in the following decades, causing Suresh to age more slowly as a side effect.

He was managing the same restaurant by 1924 when Susan and the Doctor, finally restored to solidity, came in. (PROSE: Indian Summer)
