A Taste for Death (O'Donnell novel)

Willie Garvin is nearby and he intervenes, killing the two gunmen, and incidentally determining that they work for Gabriel, the villain from the first Modesty Blaise book.

Back in England, Modesty encounters Simon Delicata, a huge man with an ape-like build, and strength to match.

Literally in fact; Modesty has to defeat the fencing master Wenczel in a duel to the death, and he's wearing a protective steel mesh jacket.

The final fight, set in an abandoned Foreign Legion fort, occurs with Modesty incapacitated from a serious sword wound and Willie having to go one-on-one unarmed against the man-ape Delicata.

The cast starred Daphne Alexander as Modesty, Carl Prekopp as Willie, Alun Armstrong as Tarrant, Sam Dale as Delicata, Geoffrey Streatfeild as Steve Collier, Samantha Dakin as Dinah, Alex Fearns as McWhirter, Jeff Mash as Skeet Lowery and Nigel Anthony as Sir Howard Presteign.
