"Digestive trouble," said Percival promptly. "There's already been rumours about, and you'll be doing a public service by going to dock with dyspepsia. Binnie will be so stricken by remorse that he'll at once start providing the Mess with decent food."

"Then for your sakes I'll rehearse the symptoms. But my curse will be on your head if I get to the wrong hospital."

It was unfortunate that the M.O. was in an unsympathetic mood next morning. He thumped Frederick on the lower chest and pooh-poohed the idea of hospital. "All you want is a few of these tablets," he said, "and you'll be fit as nails in a day or two."

Frederick crawled away dispiritedly to confide in Percival. That sapient youth counselled perseverance.

"You must go right off your feed," he said. "Let the doc. see you feebly pecking and he'll soon get alarmed. In the meantime I'm off to give Binnie critical accounts of your appetite and send him to market right away."

Only a burning passion and stealthy bars of chocolate could have sustained Frederick through the next few days. To sit down to breakfast with a healthy appetite and refuse his egg and rasher put the biggest possible strain on his constancy. His task was made doubly difficult by the scheming of Percival, who was constantly inciting Binnie to procure fresh delicacies.

"You've crocked poor Freddy," he said; "and there will be others going the same way if you don't improve the messing. Now I saw some nice plump chickens to-day in the...."

Thus harried, that evening Binnie provided a dinner that almost reduced Frederick to breaking-point. Only the fact that the M.O. was sitting opposite gave him strength to refuse the soup and fish, to trifle with the chicken and turn wearily from the sweet. As the savoury was being served he caught a scrap of conversation across the table.

"... to the boat to see her off for demob.," the M.O. was saying to the Padre. "Jolly nice girl—Jim Carruthers' daughter, you know."

Frederick pricked up his ears.
