School of Suetonius (4)

I believe the answer is:

eton

'school' is the definition.
(famous UK public school)

'of suetonius' is the wordplay.
'of' indicates the answer is hidden within the clue.
'ETON' is hidden within 'suetonius'.

(Other definitions for eton that I've seen before include "Noted public school" , "learn here?" , "School; jacket type" , "old school" , "Famous college" .)

I've seen this clue in the Evening Standard.
