Don't go on about it. Dad. It only make me more jumpy. What time do we leave here?
I've worked that out , he said. We must enter the wood about fifteen minutes before sunset. If we arrive after sunset all the pheasants will have flown up to roost and it'll be too late.
When is sunset?
Right now it's about seven-thirty, he said. So we must arrive at seven-fifteen exactly. It's an hour and a half's walk to the wood so we must leave here at a quarter to six.
