Cruise to Mauritius to start? (3)
I believe the answer is:
tom
'cruise' is the definition.
(actor Tom Cruise)
'to mauritius to start?' is the wordplay.
'to start?' suggests taking the first letters (I've seen 'to start' mean this).
The initial letter of 'mauritius' is 'm'.
'to'+'m'='TOM'
(Other definitions for tom that I've seen before include "Pig-stealing piper's son" , "He is associated with Dick and Harry" , "Waits, perhaps" , "Very small person" , "Boy running off with pig" .)
