吸声

吸 = 及 + 口 : Just when Marie Curie (xi) and Yuwen Huaji (及) were on a space trip in front of the space station (Ø1) they encountered an emergency: the failure of their oxygen supply. Their last hope is a hollow mandarin (口) they brought, out of which they suck (吸) their oxygen.

声 = 士 + 尸 + 丨 : Sherlock Holmes (sh) hears the terrifying sound (声) of bone (丨) on stone in front of the engine ((e)ng1), and he's sure that there must be a ghost (尸). Indeed it's only the bachelor (士) who wants to scare Sherlock.
