His first call was at the flat in Edgware Road which Odette Rider occupied.
She was not at home, and the hall porter told him that she had been away since the afternoon of the previous day.

Her letters were to be sent on to Hertford.

He had the address, because it was his business to intercept the postman and send forward the letters.
"Hillington Grove, Hertford." Tarling was worried.

There was really no reason why he should be, he told himself, but he was undoubtedly worried.

And he was disappointed too.
