"I will describe to you what has happened," Jackie continues. "Maybe you can get help on the radio?"

"Sure. Go on," Terry shouts back.

"It is like the grippe, that is to say, the flu, but maybe a little bit worse? Fever, chills and malaise. First Alistair, then Kerry and Tomas. I worry about Alistair, he coughs and there is blood."

"Oh my stars," Terry says under his breath.

"Brendan was also sick, some days after we left Buenos Aires. But he is fine now."

"Maybe," Terry murmurs again. But to Jackie he shouts, "Okay. Keep going."

Jackie pauses, then shakes her head. She shouts to Terry, "No no no. I think your companion has something to say?" - looking at you.

What do you say?

<> "We need the details: when did each person fall sick? Are their symptoms different in any way?"

<> "Look, this is silly. Let me come aboard and examine the sick people myself."
