Doctor in the House
Floating Profits (6x6)
:
Dick is running a late night poker school and a money exchange for passengers but collapses from the stress of it all and needs bed rest. He gets Duncan to take over but Duncan fumbles the exchange, giving the passengers overly generous rates and is hopeless at poker, losing to Captain Loftus, who finds out about it and wants to be included. Finally Duncan collapses from exhaustion - as does the purser.
