CLEM had to go and get his gas mask early, on his way to the office, but the rest of them went at half-past one, hoping that the lunch hour would be less crowded.
"And you can do military," Maxie announced, extracting from his gas mask case an old tin flask clad in khaki cloth and a packet of Bath Oliver biscuits.
But the thought of pulling the gas mask off and putting the harmlessness of the air to the test left him cold.

He had his gas mask case open on his lap and was consulting a mildewed notebook by the overhead light while he issued a string of casual orders over a cellphone:
And if Bogey had ever had to storm the regal staircase to our waiting area, this was how he would have done it: three weightless bounds with his gas mask case slapping at his side.
