Whiffy Newton in The Riddle of the Two-Tone Trousers — Rebecca Lim

Someone is stealing all the trousers in Kentwood and, this time, Whiffy's hapless inventor father, Dr Bruce Newton, has nothing to do with it. Or does he?

Trousers are being daringly snatched in broad daylight, taken apart, and horribly put back together, so that bizarre, two-toned trousers are appearing all over town -- sinisterly nailed to the front doors of some of the city's wealthiest socialites.

Who is behind these ghastly garment murders and what does it all mean? Can Whiffy and the other intrepid members of The Agency stop the perpetrator before there isn't a decent pair of slacks left in the whole of Kentwood?
